About that mystery third clamping point: How about the captive nut on the firewall which is right over the battery? I feel like it is ideally positioned to hold ONE battery cable as it comes off the battery terminal - the one furthest to the outside of the car on the left - but seems rarely used. Possibly because of different batteries being retro-fitted?

 

Thanks Alan ! Your input made me go through all the S30 variations. I think the mystery third clamp , the captive nut might be for the bigger battery flame. Japanese S30 series cars were able to have bigger battery for cold area .
Looking at the picture of the Australian magazine, the RHD export model , the battery is bigger one just like the one for the LHD model . 
 

And also  I come to a conclusion, up to around 1971 cars have only three bolt on clamps for the battery cable , after that , they became four of them . 
I looked up the parts catalog 1969 / 1970 / 1972 /1974 both export and domestic. The description says they are three of them in 1970 version but they became four of them in 1972 version. 
 

And this is my guess , Z432 and Z432R would never use the one at the underneath of the choke cable because of existing of the stand - off bracket. So , they are two of them up to 1971 , then became three of them . So , back to my first question, 1974 Fairlady Z series parts catalog says three for Z432 , four for all the other model . That is correct!

Is that Rally Car 8D-420? There's a glare just over the number.

(edit: somehow miraculously worked my way through the on-line screens of the SAN EI publisher, and bought an online version.  Great books! BTW, yes: 8D-420, which is the car featured in 1/71 Auto Sport.  They've made a few changes to it after the photo shoot, prior to this show.) 

Hi , is this car the same car of Auto sport 1/71 ?

Certainly the bigger battery was standard on Euro & UK models too, so that captive nut was used for the battery frame. I have the same on my '70 Fairlady Z-L, and have fitted the larger size battery, so use the captive nut accordingly for the battery frame. It just looked to me like it could have been a candidate for another cable clamp point when using the smaller (Japan size) battery, which stands away from the firewall.

  I think you've got it! Noted accordingly.

Yes! Kanri number '8D-420', as shown in the January 1971 issue of Auto Sport Japan. Wonderful car!

This time on 'Trade'/Test temporary license plates no less. Issued in Yokohama? Factory test car.

Thanks Alan !  “8D-420” , I really love it . The oil filter is red , and inside of the bonnet is also red , interesting!

Great to see an overhead engine shot of the left fender. I would love to have spent even just 30 minutes with this car.

Great job on sleuthing the various battery cable setups, Kats!  it might have been simpler to just route the cables across the mid-section of the cowl, to avoid the linkage. and heater hoses. It does work when in it's proper position, but it's a very tight fit. 

What car is this below?  This is different from the others, as if the standoff is longer and positioned lower on the cowl. Or perhaps I'm just imagining things.

In the 1/71 Auto Sport feature, '8D-420' does not have the satin/matt black anti-reflective paint on the upper surfaces of the front fenders, bonnet and cowl. I'm guessing your photos show it at a later date?

That oil filter looks very red. Special type? At one point the Works team were using orange FRAM oil filters (certainly during the 1971 RAC Rally here in the UK) but this doesn't look like a FRAM. 

Is the article from a 1971 issue of MOTOR FAN Magazine Kats?

So you'd say the date order is this?

1) Auto Sport pictures

2) Pictures above

3) Racing Auto Show pictures

 

Also of note: I can't say if it has to do with the photo resolution, but the left light bucket is remarkably well fitted to the fender.  There's definitely a cut line in later photos, so perhaps its a result of an overly generous paint application.

... also, I just noticed that they must have removed the left side-marker. No wonder the fender looked so clean to my eye.

 

{edit: I reviewed the Auto Sport pictures, and can see that the cut line is there, and that the left marker is missing.)

Notice it has no emblem ('Datsun') on that left fender either. Possible damage repair?

I do see the join line between the fender and headlamp cowl, but it is very faint. Possibly a lot of paint, and - as above - suggesting a repair?

 

Largely due to that 1/71 Auto Sport article, '8D-420' has long been one of my dream cars. Big influence on the project I'm currently building.
