Again, without wishing to impose impertinence and risk slanderous lawsuits and cold-shoulders, can these round 30 be shown, be proven ? The mythical figure bandied about in the world is 420 until some geezer from North London (and I repeat, North of the Thames) quietly slips in a new total whilst quoting 420 as that quantity SOLD to the public !
I think around 420 total 432s and 432Rs
'sold' by Nissan ( not all to the 'General Public' ) is a fairly well accepted figure from
those in the know these days ( note that this does not necessarily include me! ), but it is also known - by insiders of the period - that 432s and 432Rs were turned into race cars in-house and / or provided to race teams in complete or semi-complete state. It looks as though
that figure is around 30 cars and / or 'identities' - hence a total of something like 450
built.
I know it all sounds rather cryptic, but this was
Nissan's business and not ours. The machinations of deals between different sections of the Nissan organisation would have been hush at the time ( for good reason I think ) and you can imagine what the beancounters would think of it all if they were allowed the opportunity to get a handle on it, let alone a physical paper trail. It's not actually any of our business, even after all these years.
No, the 432 and 432R numbers don't include any works rally cars. Even though the pre-'72 season build 240Z works rally cars used some 432R-type body pressings, FRP panels and componentry ( and you could be forgiven for calling them 432Rs with L-series engines ), they were
not given 'PS30' prefix firewall stamps - which stands to reason, given the homologated model was the HS30 and HLS30.
'PZ' and 'PZR' are internal-use Nissan 'nickname' codes for those models. There's no spelling mistake. You see this used in period internal Nissan literature, and it's really just a type of informed shorthand that makes a lot of sense when you see more of it. Other acronyms are 'ZS' ( also seen as 'Z-Std' ), 'ZL', 'ZA', 'HZ', 'HZA', 'HZS', 'HZG', 'HZGA', 'HZSA' etc etc etc.......
I think you could pretty much guess what they all mean, even if you don't have the literature in front of you.
