Hi Mike, that is a good question, we can think the Factory A/C was available from the beginning, I mean from Oct 1969 for Fairlady Z series. Because, the very first catalog listed the A/C as an option for S30 (Fairlady-ZL ) , and the Service Shuho ( service bulletins)which Alan posted is dated at Nov 1969 . Mike , I was wondering too , the book dated July 1970 . Why ? Then I red the Forward again . It says “ the car S30-C which is designated for this A/C has been installed the system in the assembly line . However, cars other than S30-C are going to have the A/C as an option, then installation must be done at dealerships. So please refer this book for your installation “ . This leads to me a picture in my mind like this , when S30 cars were introduced A/C system was not so popular. But gradually people tended to have it for their S30 ( Fairlady ZL ) after purchased . Even some people would have wanted on their S30S ( Fairlady Z ) or PS30( Z432) which were regarded as cars they “ can’t chose A/C “ on the catalog . To accommodate those cases , Nissan issued this book making the installation easier for dealership mechanics. I think like this , what do you think of it? About S30-C , I studied a little bit . In the Service Shuho , we see Nissan gave a specific variation code for the car equipped the A/C on S30 , that is S30C ( C stands for air-Con I think) . Type code ,classification code , these are the matter of Japan Motor and transportation ministry. And those are interpreted into specific numbers and they are indicated on the registration/certification paper . A variation code is Nissan in-house code thus not shown on the paper . Having the A/C in S30 had nothing to do with Type code and classification code , so no need to declare for amendments of the paper. ( if you swapped Engine, or changed length/ width etc that is going to be a subject of the amendments ) About S30-00002 , I don’t know when the car had the A/C, I am very curious about it too . Kats

Hi Mike, where did you get the book ? I am so surprised that you have this copy which might be one of the rarest things I’ve ever seen. ( I had to buy a set of six books to buy just only this copy for 100000 JPY! I sold the other five books for 60000 JPY, so crazy expensive 😰) . Anyway , we will see how wonderful Nissan factory A/C for S30 series is . And interesting to operate! First , we need this face panel to have it in our cars. Kats PS : As you mentioned above, this A/C can’t be installed on Z432 series (PS30&PS30SB) , it is described in Forward. Literally, no you can’t. But That doesn’t mean “never “ because the system was designed for L-series engined car , however piping and assorted parts under dashboard area are nothing changed. So it is possible with some hand craft works for engine Bay Area . All the things in the system can be installed as they are , except compressor mount bracket, condenser ( need to be much smaller to avoid the air cleaner box and the coolant reservoir tank ) and the FICD (it was only designed for L-series) .I don’t know why Nissan quit making A/C for Z432 , but the A/C pulley for S20 is a good souvenir for us . Kats

Hi Gavin, we need to look at the car soon , I am surprised it was such a long time ago ! When omicron goes away , I will ask my friend to see the car in person. A few years ago he said S30-00002 was still there and covered just like the pictures. Kats

Hi Kirk , thanks! Was your 70 Fairlady first purchased in Aomori ? If so and if it doesn’t have an A/C , it makes sense to me because northern Japan people didn’t need an A/C especially those old days . Or even hotter regions, factory A/C was 200,000 JPY , it was certainly expensive for Japanese people at that time . Z-std was 930,000 JPY , an A/C costs Nearly 20% of the car itself. Kats

Thanks everyone, I ran out “like button” ! I need a jet fighter aircraft, I want to reach my room and show what I have for you, now ! Kats Oh , S30-00002 has air-con too ! You can see the beautiful check valve junction, one of the coolest looking piping and connectors among cars around 1970 .

Thanks Steve , you helped Matsuo san for the presentation, must be wonderful time for you ! Yes I would love to post pictures here when I am home , they are so interesting to see I guarantee it. I have heard it was not easy task to have the system in dashboard because it was so small room for the system. Matsuo san or Uemura san ? Told us Toyota 2000 GT couldn’t have it in a dashboard, but on the rear deck behind the two seat backs, a big box dominated the space . It was not cool at all . 260Z and 280Z have a factory installed air-con system, I am feeling those system were updated version of Fairlady Z series air-con system from Oct 1969 to Aug 1973 . But basically the same, both systems use vacuum power to move the inlet doors / airflow direction flaps . Kats

I am also thinking about “Nissan genuine air-con “ which was offered only in Fairlady Z series . I assume no Datsun 240Z was offered it from the factory, but look at pieces of the components, I am convinced that Nissan engineers were considering it would have been also available for LHD export market . I have been collecting parts for whole system and mostly done. Some parts are just fit into the existing components and some other parts needs just a little work . That is why our LHD 240Z has some “ not used “ brackets on the heater box , pre-cut on the fire wall insulator pad . So , “PLS30” with a factory in-dash air con system , a combination of sportier performance with comfortable cabin would have made the car to be a gorgeous GT . Surprisingly S20 has a special crank pulley for air-con with a part number E4200 ( Z432 oriented) , but I can’t see other air-con parts specifically made for Z432 . Nissan never officially offered air -con for Z432 . But I have seen some Z432 have the system using from Fairlady ZL system . In 1970 , it could have been around 6000 USD ( based on 1 USD for 360 JPY) , no more bargain price? What do you think? Kats

Thank you so much Alan for sharing a cool picture! Kats

Hi Ian , what a surprising thing this is ! I was going to miss it if you wouldn’t notify us . This is the earliest version as it doesn’t have a small pipe which is sticking out from the rear top surface, for the blow-by tube from the valve cover . A buyer need to source a Darin plug and a tube at the rear bottom, and four pieces of brackets ( three for the long heater outlet hose across below the three Mikuni carbs, one for the fuel supplying tube from the strainer). Kats

Yesterday, my #2146 did a fuel dumping at Fukumoto san’s work shop , the fuel was so stink , and very sticky. Just a little inspection by fiber scope , I see some rust in the fuel tank. Now I am thinking an old pipe dream again. Or do I stick with a stock ? I tend to think having fun with a S20 . Kats IMG_3941.MOV

Hi Keith , Mr.Uekubo is a very passionate about Z cars , but not so interested in showing his work. But he had been taking pictures step by step , and they became into a big photo album . I was so amazed by it . Now I have got my another blue on blue , I may not be able to do like Mr. Uekubo , but trying to do myself as much as I can . First , cleaning inside , found some coins and tickets. Maybe someone thinks me I am idiot smiling about these fatale broken seats . But for me , they are an early “ thick padding “ seat backs which has so beautiful shape .And they are blue ! For me This is for the first time ever seeing blue original seat actually . My previous blue car already lost blue seats when I purchased, so I was waiting for this opportunity since 2000 . I am so excited . Kats

Hi xs10shl, I didn’t know that there are online books ! It must be much better quality of the pictures, I think. And The car 8D-420 , thanks for clarifying it for us . Now I have a question , did the car raced in Monte Carlo? The Caption says “ raced in Monte Carlo “ , I was thinking 8D-420 was a test car . I am dreaming about this car would still be sleeping in someone’s dark warehouse . Kats

Thanks Chris! Kats

And this , approximately 200 USD for a set of six books . Tokyo Racing car show . Just a minute ago, post man rang the bell and I have opened it with a great excitement . Kats

I highly recommend that you get this book for your library. It contains a lot of pictures which were taken at motor shows in late 69 and early 70 . We can see the details when the cars were fresh right from the factory. And even more , there are special photos which are provided by Alan for the part of rally cars ! Kats

Hi Chris, this tool set is very unique, and they are new! What a great stuff you have got . I don’t know “SANKI “ , I will search it by internet, maybe a tool company? The black bag and screw drivers looks very old fashioned, so maybe they are for the earlier cars than S30 series? Interesting ! Kats

At Nissan HQ Yokohama gallery . Mr.K was interviewed accompanied by Sunshine yellow 240Z . Every time I visit there , I spend an hour or more by looking at cars , books with coffees . Children stared new Zs , a nice car can draw an attention from everyone . Kats IMG_3899.MOV

I was missing the point why our Z cars are so wonderful. Adorable price which comes from every single cost control. Minimum change makes a lot of profit, very clever ! Kats

Hi Mike , I didn’t know that , Thanks! I think Nissan just didn’t want to do new drawings, simply lazy 🤭 I found another good example in the early manual , it shows a different jack handle which was never provided for our cars . Finally in the March 1971 book , Nissan corrected about the handle but just painted it on the old early picture , not revised with a whole new picture . You can see artificial paintings for the jack handle to look “correct handle “ for our cars. Additionally, now I see why export owner’s manual show this picture of tools , which is not the same bracket and jack retainer of our cars . This picture came from the one in the early Fairlady Z owner’s manual. Kats

My 03/70 has the same as yours , perpendicular style, no NISSAN MOTOR logo . And a letter “J” on it . I edited “ perpendicular “ to “ parallel “ vice versa in post #23 . By the way, your jack has “P F 1 “on the basement, that indicates your jack is original matching tool with your car , great! Kats

Just some references for the tools , they are excerpted from Fairlady Z owners manual Nov 69 May 72 late 71 ( written in English, probably for military officers stationed in Japanese base , etc) . Please enjoy some unusual things for the tool stowage area. And we can see the lady ‘s grip looked natural for the perpendicular tooth wrench in the Nov 69 version, on the other hand, the lady’s grip looked good for the parallel wrench in the May 72 version. And I think it is interesting the spark plug wrench which was standard for Z432 is seen in the Fairlady Z owners manual English version , no other manual showing it . Kats

It is interesting! Each “ NISSAN “ has different font . Kats

Hi Chris, super cool wrench! What does “31” mean? I saw a alphabet letter D on a Nov 1971 240Z . And I believe you said there is a difference between early and late on the jack handle , didn’t you ? Kats

I am glad that your car is corresponding to your tools ! I miss American beers so much . And the video , I really love it! Kats

Cliff , my June 1972 car is a Fairlady 240ZG , so it has different chassis number , HS30-11861 , L24-114120. Your 72 240Z reminds me my ex 240Z when I was temporarily staying at Bakers Field CA . Kats
