Anyone can add or correct if you find something needed.

Even the factory manuals have some errors!

Thank you every one! A lot of imputs make this thread alive!

Gav240z, your 240Z has an unique holder, same as the picture and Z432 too. I think this holder was shared with SP/SR roadstar, was not it?

In this picture, we see the wheel was for a SP/SR roadster because it has cap teeth ! 

For Z432 , if owner chose 5 magnesium wheels , the spare tire holder was chosen this (like a tap of fire pump) , shape of the center hub can not

accept a dish holder which is used for a steel wheel. Some owner chose a steel wheel for the spare tire, to reduce price.

My elder sister PS30-00087 has the tap holder, but slightly different from mine. The yellow Z432 is PS30-00013,my Z432 has same tap as 00013 (I added  a rubber sheet  I do not want to scrach  center hub) . And my blue 1970 240Z.

Digging up an older post -

My Z432 had a conventional spare tire hold-down in in it when I purchased it in 2010, so finding a more suitable hold-down for a mag spare was yet another item on my 10-year-old wish list.  A cheap, rusty hold-down which looked the part popped up on Y!.yp a few months ago, and I paid something like $40 for it, with another $30 to have it shipped. 

I'm not entirely sure it is the exact S30 Z432 part, as it's been mentioned that it might be shared with another model, but it seems to do the trick regardless.  I'll have to add a rubber cushion prior to using it. It cleaned up fairly decently (photos of bare metal part attached), and will be sent out for cad in my next batch.  I'm assuming it was Yellow cad, and not originally silver cad?

... my First Law of Acquisitions predicts that I'll stumble across an authentic piece within a month or two.

Sure enough, a few weeks later on Y!.jp, up pops this piece for less than $200. Looks authentic enough.  Now I have a spare.

I worked for the Z432 tach which I want to make it being works look. 

I want that works style 6 o'clock tach! Lovely piece of kit.

Did you have that tach face custom made?

Hi Gavin, the tach is genuine one from Nissan sports optional parts. I combined its face and needle plexiglass with a standard Z432 internal mechanisms. If I had a optional igniter called “orange box “, that could drive the sports option tach.

Hi, you got very nice stuff for your Z432, they are hard to come by recently. I have seen some silver cad tire hold-down tool so you are having correct color for it. 
 

And the intake air duct, it will be a nice spare for you as a Z432 owner. By the way, do you want a complete set of oil cooler system? Also a S20 works version valve cover (machined plug cap holders with special plug wires) is available. 
If you interested in, please let me know.

Here is my oil cooler for my Z432.(they are not for sale, the one on sale is a different one )

I have found there are two different types. The one has 18 cores while the other has 14 cores. Which one is older? I have seen 18 version was used on some works Z432, but haven’t seen 14 version yet. 
Maybe works rally car has both types?

Do the oil coolers mount to factory points?

Nice parts Kats!

I'm not sure which is the best way to count the cores? Do you count the sections (cores?) or the joints? I would suggest the sections are the actual cores?

I can't remember how many sections are on the two 432-R coolers I've got, but I'll count them. I also have a Works 240Z rally cooler and I count 19 sections (cores?). Here it is in period, still attached to the (heavily crashed) car that it came from, one of the 1973 Monte Carlo Rallye cars, built in 1972:

Yes, there were dedicated mount points in the radiator sore support panels. Top mounts required brackets between the (captive nut) mounts and the cooler and bottom mounts bolted straight through the core support.

The top mounts have a certain amount of 'spring' built into them, which is most likely designed to give some vibration damping effect?

Here's the cooler on my 432-R replica project car:

[26th-Z]

A core is the galley by which the oil flows through.  At first, I noticed a difference between the top brackets.  One side mount and another top mount, as you show, Alan.  But I see both side and top on the 18 core cooler, so...
