I've not seen a reply with the correct model designation for this car. Nissan Historical Collection indicates the model code is "S30" rather than one of the other codes ... HU or whatever ... :-\
I asked because I thought someone might have the "real" answer.
But Kerrigan, this is exactly
the type of thing I'm talking about when I refer to the frustration in trying to help you.
You've been a member on the classiczcars.com forum since August 2003. On the classiczcars forum I - and several others - have documented, discussed and argued about the Japanese market models for something over 12 years at least now. I myself have added lost of photos, scans and text containing accurate data about those models. The 1971 Fairlady Z-L is one of them. I own a 1970 Fairlady Z-L myself, so I had a greater incentive to find out more about such cars and - particularly in the case of one or two USA-based "experts" who see them as "irrelevant" - to defend them as significant variants that are a key part of S30-series Z history. Katsuhiko 'Kats' Endo is another who has added valuable information to the forum, in particular period data from Nissan Shatai ( the company which actually built
these cars ).
So why haven't you picked up the correct factory model designation of your car from those discussions? The factory build codes are something I feel like I've written out a thousand times on various forums, so what's the big mystery? I know for a fact that you have participated on some of the very threads where such topics have been discussed in depth...
The basic model code of your car is - simply - 'S30'. In factory parlance it was variously nicknamed the 'Deluxe' and/or the 'Dx'. On factory parts lists it is sometimes called the 'D' model, or 'Z-Dx'. It shared the 'S30' chassis number / body serial number sequence with the 'S30-S' model 'Fairlady Z', a cheaper - no frills - model that came without hubcaps, bumper rubber trims, carpets ( it had rubber mats ) and even without a clock. This 'Fairlady Z' model was nicknamed 'Z-Standard', and 'Zs', 'S' or 'Z-Std' depending on which factory publication you refer to. And as the 'Std' and 'Deluxe' models shared that 'S30' prefixed body serial number sequence, there's no way of telling whether a particular car is a 'Std' or a 'Deluxe' just by looking at the chassis number. So, for example, a car with a theoretical chassis number of 'S30-00023' could be either a 'Deluxe' Fairlady Z-L with all the bells and whistles, or a basic 'poverty' spec 'Standard' Fairlady Z with a 4-speed. It gets a little more complicated after that:
Now, there were
suffixes to these basic model codes, and these suffixes - mostly used by the factory and the dealers - identified particular sub-variants. For example, a Fairlady Z-L equipped with an automatic transmission would be coded 'S30-A' and a Fairlady Z with an automatic transmission would be coded 'S30-SA'. A Fairlady Z-L equipped with an automatic transmission and
prepped for 'Regular' gasoline ( as opposed to High Octane ) would be coded 'S30-AN', and a Fairlady Z with automatic transmission and prepped for Regular gas would be coded 'S30-SAN'.
However, these suffixes were only noted on the factory paperwork and the dealer's paperwork. They were not noted anywhere on the car ( although there were clues to them... ) and you will have to piece together the original spec of the car ( and therefore the applicable 'Shashu Kigo / Shanai Kigo' ) from the evidence presented on the car itself. With a 1971 Fairlady Z-L that's actually fairly easy:
Take a peep at the attached scan. It's a official list of Nissan's S30-series Z models as of October 1971, when the L24-engined models ( with HS30 prefixes ) were introduced and sold alongside the previously available L20A and S20-engined variants, giving a prospective buyer no less than 20 variants to choose from, all of which could be up-specced from a fairly comprehensive list of dealer options and official 'Sports' option parts.
The third column contains numbers that - to Nissan at least - identified the sub-variants properly. These numbers are the 'Ruibetsu Kubun Bango' for each sub-variant. If you can pin your car down to one of these then you have your answer. As I'm guessing it came with a 5-speed trans, it's either an S30, S30-C, S30-N or S30-CN. If it had factory aircon it's an S30-C, if it had Regular gas prep it was an S30-N, if aircon AND regular gas it's an S30-CN. If none of the above then it's a 'normal' S30 code Fairlady Z-L.
If any specific questions, fire away...
