Wonderful! O. K. D is 1969 November 4th for the Jack 9 L is 1969 December for the chocks. It is nice to see these examples as they happen to have the tools a little bit earlier than car like yours .Kats

Hi , today I would like to show you this , a NOS trim panel for my car . Thanks @SteveE, I appreciate your great help . This piece is now very hard to see in this condition, not only for the early car style ( non-access panel type ) , also this is a blue panel ! I can confirm the real color when blue cars left from the factory . Next time I do some work for my new blue 240Z , I will show you the difference of color between two of them , old and new . I need to work for the car as it deserves this beautiful piece. It will be a long way . Or I will put this on my -2156 until -2146 becomes beautiful. Kats

What ??? Why does YouTube prohibit seeing American rock video in your American home ? By the way , has Nissan USA ever used their song for TV commercial? I just imagine and it seems to me their name “ ZZ Top“ is suitable for selling Z cars . Kats

I dedicate this song to siteunseen . Kats

Marshall guitar amp , is not it ? Both volumes are set maximum , I think I am hearing Hard Rock guitar solo ! Kats

Thanks xs10shl, this is a great work and I am sure this log will be a nice instruction guide for everyone who need to install the system into a Z432 , probably for GTRs ( PGC10/KPGC10/KPGC110) too . Ignition management is a key of those cars , no more new parts from Nissan today , and there is no singles part which is interchangeable with a stock L-series engine system. Even if someone has a complete , perfect S20 but without working ignition system ,it will be sad for the car and for the owner . Or like this , I am a bit fool for S20 even if it doesn’t sit on a car . Just looking at the machine, I can spend whole day of my life . Except Alan ,I don’t think we can explain about this engine. This is probably a pinnacle of existing, working of all the S20. I will report when this engine starts fire up in a car . Kats

Seems Alan and me are only people who are interested in the head light cover 😁We are in a Tokyo motor show class room , learning every day. If this was three screw type , I would like to check design prototype cars . There might be some same character for both covers . Kats

Let me see one more time , Kats

Thanks Alan! I can see three so far , where is one more located? Kats

Thanks Alan! And Chris, I didn’t realize it, E4125 , I am confused too . That is additional home work ! Here is a picture from “My car report “ Dec 1969 , do we see three screws on the head light cover ? Still mystery. Kats

I have this paper , supplemental information for optional parts for S30 series . Dated 45. 1. 21 ( 1970 . January 21st ) , just a little bit earlier than “Race and Rally manual Fairlady Z 432-R” February 1970 . I want to see if there is one which is earlier than Jan 21st 1970 . We see the first parts catalog for Fairlady Z series is November 1969 . And this catalog, there are lot of blank pages .No pages for option parts ,even no pages for keys, heater system either , etc etc . I guess parts catalog department was working so hard on publications to catch up with car delivery. I thought parts catalog was ready just in time , but it wasn’t, was it usual thing back in the days ? So , this supplement information paper dated January 21st 1970 might not be a big delay if this is a first one , I guess. Today we have internet, but in 1970, business people must have send these paper packed in an envelope and threw it into a post . Kats

Hi Gavin, I already have an image of it .Will be a big monument rather than a statue. Nissan Shatai HIRATSUKA factory is the place I think . I have visited there once with club members , “ factory tour “ . I want visit there one more time ! Kats

Thank you so much Chris! That is what I want to see . 26th and 27th both have a unique metal tab behind the passenger seat, and no- bracket ( I mean no -ordinary bracket) for the master vac hose. And I see the bar- type panel press indent near the jack holder bracket, this is new to me . Maybe it would be a signature of ultra early car , what do you think about it? Now I’m curious about when was the boundary for the cars which have this unique jack holder bracket associated with a master vac hose bracket. We need more examples. Kats

BIG THANKS ALAN !! You said it all .Your said “ Rosetta Stone “ , I am shivering with it . I am feeling that I want to make a statue of the document , and put your commentary aside. Where is the best place to display? Thanks Alan. Kats

Hi , I need everyone’s help to find out when Z432 PS30-00023 were made . What I am scratching my head for is , PS30-00028, 53, 55, 61, 62, 63 they all have a bracket for the master VAC hose . And PS30-00023 will probably be the same . I thought this bracket is not for most of the 69 cars , and PS30-00023 and 00028 look early enough for No- bracket car . The production figures which I have got Mr. Uemura and Mr.Osawa showed that Dec 1969 , 688 cars for domestic, only 97 cars for export. 688 was almost Triple of the number for domestic in November. For export, in November 388 , then stalled to 97 in December. The feedback from the test run in US & Canada might affect assembly lines , I guess they switched making domestic cars more instead of making export cars. Thinking about Z432 , up to PS30-00072 is 1969 car ( according to the Japan automobile Industry cooperation) . I was expecting approximately 25 Z432s a month from October to December. So , PS30-00053 have the bracket that makes sense to me . But PS30-00023 and 28 , were they made in late November or December? If the bracket for the master VAC hose started to attached from late November or early December, and PS30-00023 has the bracket, then we see Z432 PS30-00023 to 72 ( there would be others of course) were finished assembling in late November or December 1969 . @26th-Z @MikeB @240260280, could you show us your 1969 car’s bracket, and also I want to see the bracket for the metal band for the Jack stowed. Very early cars have this unique shape bracket on the floor , behind the passenger seat. Kats

Side note , my 240ZG has old screws, maybe originals. And captive nut for the head light case is original for 240ZG. Kats

Hi Alan, E4100 is before E4126 , I think so too. And they both have 4 screws , and the same screw positions, so there would be some small change from E4100 to E4126 ? I need to find more clear photographs of the Z432 on a display stand at the 16th Tokyo Motor show. If this car has three screws , then what part number would have been applied? There would never be earlier number than E4100. Kats

Hi Alan, I have no idea what does E4100 look like . Big home work ! Kats

One more thing, We used to , We were thinking E8726 is the early one . Due to its screw positions, it was very common to have crack on the lens at the front edge . Like you showed us , the location of the front edge is somewhat difficult to fit without certain gap . Then if the screw tightened more than needed , it cracks the lens . Then we thought, that is why Nissan changed screw positions not to have a crack over there. The E4126 seemed developed one . Today we know that story can’t be applied because we know the part number tells us which one is early. So what was the reason for changing the screw positions when Fairlady 240Z-L introduced? This is my guess, E4126 was likely having moisture entering into the cover lens when it was in the rain or snow . That caused loss of intensity of the head light beam . Then engineers might put a screw at the front edge of the cover lens . What do you think about it? Kats

And I would like to emphasize this , the difference of the cover lens shape . I made a poor drawings over the pictures, could you get what I am going to say ? The early-style E4126 has significant ridge on the lens which I think it has more correspondence with the bonnet , head light case . When E8726 was introduced, the screw positions were altered and also cover lens shape was changed. E8726 has lost its ridge , became much gentle curves . Not only the cover lens, also trim ring had changed its shape accordingly. Kats

Hi , I was going to put this when I saw your fine work . Long time ago , I was not sure about screw hole positions. But many people have showed many examples , now I think we have fully decided about it. The positions in your cover is the early-style, 63900-E4126 (R.H.) / 63901-E4126 (L.H.) . This is proven by the parts catalog . Those numbers were first ones shown in the catalog. And we can see the picture of them in the DATSUN COMPETITION parts catalog with those numbers. And like you showed us , we are seeing it that E4126 has the “positions “ which is regarded as “early-style “ with the original parts box . Kats

Hi , they are fiberglass version. And the screw positions are later version. The reason is ,this set of head light case was exclusively made for Fairlady 240Z-L (aka HS30 / HS30D ) which has the head lamp cover as STD . That was in October 1971 . So , the part number for CASE-Head lamp is 63115-E8731 (R.H.) / 63116-E8731 (L.H.) also you need Cover kit head lamp is 63900-E8726 (R.H.) / 63901-E8726 (L.H.) accordingly. Before the car , there was no car which has a head lamp cover as STD . And also screw positions were different. I will put some information about the screw positions . Kats

Massage, yes ! I did massage for my trim ring fit well with the cover. Just for your information, here is the one which have already nuts into the case.

Thanks Gavin , great info ! “What I noticed with HS30's (In Australia anyway) is that the 72 model year is by far the rarest model (compared to 70,71 and 73). I am guessing this is because Nissan ramped up production of Fairlady 240Z and Fairlady 240ZGs around this time period and perhaps made less HS30's for Australia, NZ, PNG, South Africa, UK, Hong Kong etc..” This is new and making sense to me . Looking at this figure , Fairlady 240Z series were approximately 1200 cars in 1972. Kats

I saw someone said Nissan only made HLS30 first , like 100 or 1000 240Zs . I would like to share this with people who are interested in how they made our cars . We have a good source. Please see this picture, a blue Datsun 240Z was followed by an orange Fairlady Z-L . Nissan Shatai was able to mix all the models in the assembly lines. However there might be some batches of certain models . Especially in a painting room , same color was sprayed for some batches of cars . Engines , they might have been the same . Kats
