HS30-H

Indeed, it translates as "Fog Lamp Switch" and other factory literature identifies them as being an extra-cost showroom option.

That's what's known as confirmation bias. The "empty hole" was designated for the optional E4100 fog lamp switch, as I have already pointed out. The E4100 fog lamp switch - literally - could not go anywhere else. The design of the switch alone dictates that. Sorry for the "single comment in a forum" (hopefully you can't see my eyes rolling....). I'm writing this after you have posted a couple of old threads - active several years before you joined the site - which discussed the factory fog lamps in some detail, with a fair chunk of the posted data coming via Yours Truly. I suggest you spend a little time actually reading and understanding it. There's gold in them thar hills... But he is - of course - mistaken. The other option is that he knows full well that the factory fog lamps were offered in markets other than the Japanese domestic and - get this - he's trying to sell you something. It wouldn't be the first time that somebody stretched the truth a little - or didn't manage to tell the whole truth - when telling us about these cars. Does "Made Expressly For The USA" ring any bells...? Here's a scan of a page from Nissan's 'R-Drive' Export market parts catalogue C-0010R. The components are - just like they were in Japan - listed as 'Option' parts: We could - indeed we have, back in the days when this forum was a little bit more engaged by matters historical than in reading spark plug runes - discuss many other monkey tail appendixes and "mystery" (to some more than others...) holes and fixtures on these cars that are there for a very good reason. As for the factory Fog Lamps, the component parts existed, the wiring was there in the harness to run them, the mounting points were pre-drilled in the front bumper to accept them and the indentation and doubler was there on the dash to accept the switch, from October 1969. Yes, they moved the Cigar Lighter up there later. Doesn't mean that they wanted it there all along. I think the problem here is that you have come up with a theory and are now engaged in shaping evidence so that it fits. Sorry but your 'F Knob' theory isn't even going to float, let alone fly.

That's a rather bizarre take. By implication, you therefore think that the original position of the cigar lighter - as seen on the cars at launch - right next to the ashtray was some kind of compromise? That they were just itching to put it up above the hazard warning switch in '69 and even reserved a space for it there, but just couldn't get it done for a couple more years...? Have you been sneaking a peek through the patent Beck-O-Scope? Nope. The reserved position for the optional E4100 Fog Lamp switch was above the Hazard Warning lamp switch and the wiring was in the dash harness behind it, ready and waiting.

But that's not what is being discussed here. The yellow marks were applied on the production line to show that a check had been performed, that's all. Nobody was checking them for movement anywhere after that. Tell-tale markings - as used on race cars, for example - are a different thing. Usually thin stripes or dot points on adjacent components that can be quickly checked by eye. Like this:

No. It indicated that the fastener had been torqued to spec on assembly and checked. Nothing after that.

Won't win any prizes for photographic excellence, but here's an E4100 NILES early-type Fog Lamp Switch in its correct location on one of my other cars:

That particular car has an S20. There's a pump between the 100 litre main fuel tank and a sub tank, then another pump between the sub tank and the engine.

Certainly not S30-related, anyway. The 'early' E4100 fog lamp switch is a two pin NILES unit in the same 'flip' format as the Hazard flasher switch. It has a graphic on it rather than a letter. Here's a pair of them being used as fuel pump switches:

No, different thing. Japanese market variants had a road safety-related system which allowed extra bulbs in the front and rear lamp units to be illuminated whilst the car was parked/unattended on a dark roadside. The lamps could be switched to illuminate either the left or right side lamps - or both sides - by means of a combo switch on the centre console (as illustrated in my previous post). All Export market variants carry the vestiges of this system, evidenced by the switch space on their centre consoles and the nascent extra bulb holders in the basic design of the front and rear lamps.

That's a Heated Rear Window switch and double Parking Lamp combination switch set for the ('early') A-type transmission consoles. Like this: Not what he's looking for, unfortunately.

Indeed. I've been on a steady decline in quality since 2002... The E8700 Console-mounted Fog Lamp Switch was a rarely-specced showroom option part in Japan, and only available for a relatively short period (roughly early October 1971 through late August 1973) after which the design changed completely. I see the part number quoted also on the relevant R-DRIVE Export factory parts list, but the only illustration is the (equally rare) earlier type dash-mounted E4100 NILES two pin 'flip' type fog switch. There is not even a drawing of the E8700 type. The March 1974 update of the R-DRIVE Export factory parts list gives the following part numbers: *25370-E4100 COMP-SWITCH FOG LAMP - up to 08-71 (Note: this is the dash-mounted NILES two pin 'flip' switch). *25370-E8700 COMP-SWITCH FOG LAMP - from 09-71 (Note: This is the console-mounted Droid you are looking for...). *25370-E8701 COMP-SWITCH FOG LAMP - from 07-73 up to 08-73 (Note: The fog lamp switch that burns twice as bright burns out a month later...). *25370-N3400 COMP-SWITCH FOG LAMP - from 08-73 (Note: This is not the Droid you are looking for...). To be honest I've never really sought out an E8700 type switch as I never needed one, but it seems that they are rather elusive. I've got several of the equally elusive E4100 type but I don't recall even seeing a photo of the E8700 type in Japanese market factory literature. The only pictorial reference I have is the factory parts list drawing I posted in the 2002 thread. So, can't help, not won't help.

You probably already have this data (?), but the March 1976 dated Nissan Sports Option list for the RS30 and GS30 models includes the E4622 suspension kit. It shows that they still used the previous E4621 springs with the kit, giving free lengths for the springs as 171.5mm Front and 205.5mm Rear. The same March 1976 Sports Option list gives a part number of 55037-E4620 for a "Spacer Rear Strut MTG", stating that it is made from Aluminium and with a thickness of 20mm. Seems to fit the bill. I've seen these used on the front as well to give a little extra lift. I have some that are made from steel, but don't know if they are (later?) factory items or if somebody copied the factory items. Yes, they are the original 'Wet Leg' type dampers. If they match up with the strut tube length then I reckon they could be re-used effectively without the gas-filling (it was only there to help mitigate aeration/foaming of the oil under hard use) and indeed the early standard struts used the same system without the gas-fill (and - years ago - the 'hot tip' to upgrading these was to replace the factory type Nisseki A-1 oil with a heavier grade oil) as long as you are not planning on heavy track use...! They are actually very nice to use and I reckon the thicker piston rods are a boon. A friend of mine in Japan made up a system to re-fill the gas charge (he added a valve on the lower body) but it's a real hassle. On the other hand it is easy to convert these struts to use cartridge type dampers as long as you choose the correct length of cartridge (and Bilstein would be nice!). I've had Nissan Sports Option (and even some Works rally version) struts through my hands in the past which - when opened up - revealed aftermarket cartridge units inside. Obviously replaced some time in the past. Yes, those springs are not correct for the Sports Option adjustable platforms. They should have a flat lower section to sit on the platform. You can get springs made to suit the adjustables. There are certainly companies here in the UK who can make to spec. Let me know if you can't find a supplier.

Hi Nils. You've had some happy hunting again I see...! Your ATSUGI Sports Option front struts look just like a pair of E4621s that I've got. They are oil-filled but gas-charged to help stop the oil from foaming. Don't let the gas out! Those red-painted rear legs also look like Nissan Sports Option items to me. The welded-on (steel) threaded sections are very characteristic. The strut tubes themselves look very long so I'm wondering if they might be the late Nissan Sports 'Rally Option' with the adjustable lower platform which superseded the fixed-platform E7220s? The part number should be engraved on the tubes same as the Atsugis.

It's an R-Factory airbox originally designed for the S20 twin cam engine. I flipped it over and used it upside down on my L24. It has integral air horns welded to the base plate. Short/medium height Mikuni-Solex/Weber type standard air horns would fit if you modified the base plate to accept them.

Hi Ian. Sorry, missed your post first time round. It looks very similar to the diff cooler kit fitted to some of the later UK & 'Euro' market cars (for expected Autobahn speeds I guess). I've got a couple of the same pumps as NOS parts and I believe they continued well on into Z31 period. Used on other models too. Factory Works rally cars used a similar pump in '73, hidden/safe in one of the tool compartments:

"Luggage Belts". You'll have a matching set of threaded holes on the floor just below the rear interior cover trim.

Would be rude not to.

By the way, fitting the Nissan S30 Alfin rear drums has been a popular modification for certain Triumph models. The Spitfire in particular. Hence the specialists such as Moss and Rimmer Brothers used to filch supplies from the UK's Nissan dealers. Now they have their own pattern supply: https://rimmerbros.com/Item--i-201246UR "Reassuringly expensive", as the saying goes...

Several other contemporary Nissan models had the all-ferrous brake drums as standard equipment, notably the C10-series Skyline. It has always been seen as an 'upgrade' (lighter weight, better cooling) to fit the Alfin drums from an S30 onto the more sporty of the C10-series Skyline variants. They are a like-for-like fit. Suitable replacement - 'pattern' - Alfin drums were still available from BREMBO last time I looked.

You did well then. Good!

Take a closer - much closer - look at the stitching detail on the "leather". I think you'll find that - just like the originals - the 1995 NISMO 20th Anniversary reissue wheels were cleverly made by Izumi to look like they were hand-stitched leather, but in fact were molded vinyl over urethane sponge, with faux stitch detail.

Door 'skins' do not - can not - carry any of the captive nuts and fixtures for door hinges, latches, locks, window frame/sash and window winder mechanism that Derek describes having difficulty with. Here's a photo of the rear side ('inside' if you like) of a reproduction replacement door 'skin' sold by Z Car Depot. It has some structure at the top which the window trim and window roller guide attach to, but just holes in the pressing for the outer door handle and lock barrel. That's it. It's simply the outer surface of the door when it is on the car. It is not a complete door: Derek and Resurrected Classics are talking about complete door shells, not just skins. Here are a couple more photos of my NOS N3400 door. If you look closely you can see where the outer 'skin' flange wraps around the door shell pressing:

You keep using the term "skin". In common usage, the term "skin" refers to just the outer layer of sheetmetal which is stretched over the door frame pressing. Nissan used to supply replacement door 'skins' (which they called Door Out"/outer, and also whole door units. They are two different things. What's being discussed here are not just door 'skins', but complete replacement door units.
