I think it's early. If the front turn signals are under the bumper, it's early. If they are in the grill, it's late.

I don't know about the rest of the world, but I believe that here in the US the rear sway bar wasn't fitted by the factory until the 260Z for '74.

Looks pretty cool. I'd like to have the early one, but I'll bet it'll go for way more than I'm willing to pay.

Oh, well. Had to ask. :nervous:

Way cool! You want to sell me your wiring harnesses? See the thread below: http://classiczcars.com/forums/showthread.php?t=19793

Here's the scoop so far. After more research, and corresponding with several possible suppliers, the two choices I listed in the last post are still accurate. Either find a replacement dash harness assembly that is the same as mine, or replace both the dash and engine harnesses together. As I feared, the harness I have now (automatic from 10/70 to 12/70) appears to be rather hard to find period, to say nothing about finding a good unmolested one. But further thought now makes me think that might not be such a bad thing, as it tends to force me to do it 'right.' You see, the more I think about it, the more I think I'd like to replace the engine harness anyway. I think my current engine harness is OK, but is it really? When the fusebox suffered its meltdown, it melted wires in the dash harness as well. Could it have melted wires even farther back into the engine harness? Certainly. Did it? Don't know. But I do know that my car does not have a fusible link on it right now (removed and bypassed at some time before I bought the car), and that makes me suspicious. So I think my preference right now is to replace both of those harnesses. To ensure that everything works, what I believe I want is to keep my existing rear body harness (24014-E4601, used on all early cars up through 12/70), get a good engine harness (24012-E4601, used on manual transmission cars from 2/70 to 12/70) and a good dash harness (preferably 24013-E4602, manual from 10/70 to 12/70). I could possibly use dash assembly 24013-E4601 (from 1/70 to 9/70), but I don't know what differences that might require under the dash. Can anyone out there think of any electrical differences between late '70 cars and the very early '71s in the dash harness area? Warning lights? Door buzzer? Something else? Edit: I've now been told that the earlier production cars (prior to 10/70) did not come with the key-in-ignition buzzer. If true, that may well be the only difference in the dash harnesses listed above. And since I could live without the buzzer, that would open more options for me.

Yeah! I like yellow on early Zs! Of course, I also like early Zs in orange, gold, red, blue...

You don't. The ammeter shows the aggregate of the output of your alternator minus the load from the electrical devices. It's going to change when the load changes.Ideally, I'd like my cars to have both. But I'll make do with whichever one it came with, it's not worth it to me to add other gauges.

Yeah, I have them on my other cars, not the Z yet. I just don't like disposable stuff. I'd rather have something I can buy once and not throw away later. I can verify that they do (or can) flow more air - when using them on a motorcycle (especially a two stroke), the carb jetting needs to be fattened up a bit. The K&N flows just enough more that they end up running just a touch leaner.

Hmm. Must be one of the very last Series I cars, with a number that high. Some good stuff there, note that it still has its original steel water-pump-killing engine fan. I can't tell if it still has headlight covers, or just the mounting clips for them. But there's a whole lot to work with there. I wonder what color it started life as?

No, they are a pair. The one on the left of the picture is sitting with the manifold side facing the camera, the other is sitting with the airbox side facing the camera. These carbs are not for a '70, they are for a '72. Note the coolant passage to the nozzle area on the left one. In general, four screw carbs were used in '70 and '71, three screw carbs in '72.

I've got nothing against silver, I own a silver car, but not a Z. I just think that yellow or orange or even 920 gold are better on an early Z. Or I should say that those are my personal faves. Absolutely. Mine isn't all that bad, rust-wise. But I'd much rather have paid more for a car like that had I been able to at the time.

Agreed. I wouldn't count on the mileage, and the seller isn't actually claiming it, just suggesting. But the body does look exceptionally solid. Probably worth it. But... silver?

I'll let the post speak for itself. 240Z on eBay

True, in many parts of the country (where there aren't emissions tests) that stuff is long gone. I'm sure mine was disposed of when they stuffed in the injected ZX L28. But if I still had it all, I'd probably still have it on the car, just because.

Yup. I used to make a living selling wheels and tires, from '76 through '98. It's a Progressive Wheel fake 'billet' style. Early to mid '90s, for certain.

I missed out on the Pinto, had a Vega instead. In fact, I bought a second Vega after I got out of high school. Being a bit of a gear head even at the age of 18, the second one was a Cosworth Twin Cam Vega, #0853 of about 3500. I wonder where it is now? For those of you who may not have heard of these critters, the Cossie had an aluminum 16 valve twin cam head designed and built by Cosworth in England on top of a de-stroked 2 liter version of the Vega's aluminum block. (Cosworth had come up with the idea to use the Chevy block as a basis for a light, bullet-proof and affordable Formula engine.) So clear back in 1975 Chevy was selling cars with twin cams, 4 valves per cylinder, electronic port injection, stainles tube headers and pumpless air injection for emissions control. Of course, they couldn't make money on it, so it died after 2 years. http://www.cosworthvega.com/ http://www.cosworthvega.com/unique_features.html

You know, when I posted those links, I could have sworn that the Aviator satin was available as a three point, but now all I see are lap belts. The three point belts are all chrome. :mad:

OK, so it looks like I should be OK with the early small booster that is now on the car, even when I add the clutch hydraulics. Thanks, Dave!

Ack! Is it possible that the automatic cars used a bigger booster? Do I need to add a smaller booster to the list of parts I need for my upcoming 4 speed swap?

Don't pull that dash harness for me at this time, I've got another idea cooking. Details later.

Ooh! Goody! I was wondering what the dates for that were going to be next year. I don't know if I'm going to have my car ready to be seen by then, but I'll be there one way or another.

Thanks for thinking of me, Enrique. Yes, I do need the dash harness assembly from a car of this vintage, but only if it is in really good shape and from an automatic. See the latest on my harness story at the end of my other thread.http://classiczcars.com/forums/showthread.php?t=19793&page=2

Here's the latest I've learned on the dash harness deal. While the two dash harness pieces are separate, and have individual part numbers, Nissan apparently never offered the two parts separately, but sold them as an assembly under a single part number. Apparently, all three major wiring harness parts (engine, dash and rear) were different on the automatic cars. It is not known whether any of the manual transmission harnesses could be successfully connected to any of the automatic pieces. It is therefore probably best for me to either find the correct automatic dash harness assembly, or to consider changing all three sections to matching manual transmission parts. Edit: Further checking reveals that only the engine and dash harnesses are transmission specific. The rear harness is the same for either transmission. So I might be able to do it with just the dash and engine harnesses from a manual transmission car. The two dash harness parts I have (24013-E4705 & 06) were apparently listed by Nissan as an assembly under 24013-E4703, listed as "ASSY-HARNESS INSTRUMENT" for automatics between 10/70 and 12/70 inclusive. This is not encouraging to me, as I fear that there won't be many possible donors (automatics in a very short 3 month period). Just in case, I called my local dealer, and the automatic harness assembly part number is no longer in their computer, and it is not listed as superseded. The matching manual transmission dash harness assembly (24013-E4702) is still a good number, but it is NLA from Nissan. So it looks like I have two options - 1.) try to find the proper (but possibly rather rare) original automatic dash harness assembly, or 2.) bite the bullet and swap the whole works to a similar manual transmission harness. Number 2 is probably the more likely option, I'm guessing.

Got under the dash this afternoon (once the ice melted - damn freezing rain), and was finally able to find the part numbers on the two dash harnesses. They are 24013-E4705 & E4706. I suspect that these two are the ones with the extra wiring for the automatic transmission (which my car still has for now). What I'd like to find out is whether there is a manual transmission equivalent to these two parts that I could use instead, since I will end up swapping in a 4 speed next Spring. Since I don't yet have the parts CD (I will buy it after the holidays, I promise), could someone who already has it look up the dash harness numbers for a 10/70 build date car, both auto and manual for me? I'm betting the auto harnesses will be the E4705 & 06, and that the manual may be E4650 & 51. If it is serial number specific, my car is #12746.
