kats Posted March 6, 2018 Share #1 Posted March 6, 2018 Hi, have we discussed about this before? I want to know the answer of these coding. Each jack has alphabetical code, I have a jack , ’ P. C. E ‘ Could it be made 1970 March 5th ? This jack is in my 03/1970 240Z. And olso the car has ‘ 0. C ‘ stamp on a tire stoppers , I guess it could be 1970. March. I saw a 09/1970 car has ‘ P H Y’ , this means 1970 August 25th ? This car still has a paper list in a tool bag, with a stamp ‘ 45 9 10’ ( 1970 September 10th) And I found some 1969 cars have ‘ O ‘ for their jack, O I A , 1969 September 1st ? O G S , 1969 June 19th ? These cars have these on their tire stopper s. ‘ 9. I ‘ 1969 September? ’ 9 K ‘ 1969 November? Kats 2 Link to comment Share on other sites More sharing options...
kats Posted March 8, 2018 Author Share #2 Posted March 8, 2018 (edited) How about these , I think Tire stopper, 0. G. 1970. July 2 E 1972 May ‘C ‘ is stamped, however ‘ G ‘ is engraved, so the change would be happened around April to June 1970 . Jack , Q. F. V. 1971. June 21st R E DD 1972 May 30th Somewhere around 1971 , jack has changed its comportments . Early one has unique contact piece and only two rivers applied to hold the basement while later ones has four . If this is true, ‘ A’ means 1954 . At that time Nissan was making Datsun sports DC-3 . I think this is one of the easiest way to guess when my car had left from the factory. And it is nice to have ‘ munching numbers ‘ those factory items. How about yours ?

Mike B Posted March 10, 2018 Share #3 Posted March 10, 2018 Hi Kats. Great job finding more potential date codes! I will check what I have this weekend and see if they match the pattern you identified. -Mike 1 Link to comment Share on other sites More sharing options...
Mike B Posted March 11, 2018 Share #4 Posted March 11, 2018 Ok Kats, this is what I have using your codes: Jacks: OCH - March 8, 1969 OIA - Sept 1, 1969 OKB - Nov 2, 1969 OLA - Dec 1, 1969 OLA? - Dec 1, 1969 (this one is difficult to read the 2nd and 3rd letters, so this is my best guess) PFX - June 24, 1970 RDM - April 13, 1972 RDN - April 14, 1972 REL - May 12, 1972 RFQ - June 17, 1972 TLCC - Dec ??, 1974 Wheel chocks: Note I was looking for only for the black ink stamps not the punched letters . I only have a couple with the black ink stamps, so will have to look for punched letters the next time I go to my garage 9J - Dec 1969 9L - Oct 1969 1 1 Link to comment Share on other sites More sharing options...
kats Posted March 12, 2018 Author Share #5 Posted March 12, 2018 Thank you so much Mike ! ! You have so many jacks, just amazing. Are they all come from your cars ? If so, Do you think my coding will work or not ?Does each car have each corresponding jack ? Rubber stamps on the wheel chokes are so cool , they are 1969 pieces ! Many thanks, Kats Link to comment Share on other sites More sharing options...
Zup Posted March 24, 2018 Share #6 Posted March 24, 2018 @kats @Mike B Finally pulled out my wheel chocks from storage. Here's what I found in the 2 sets that I remembered having. 9K and OD neither have punched markings Found one jack.Still looking for the other jacks------buried in a box somewhere------- 1 Link to comment Share on other sites More sharing options...
jwtaylor Posted March 24, 2018 Share #7 Posted March 24, 2018 (edited) My jack is stamped S D X, which is April 24 1973 if I'm doing the decode correctly. My car build date is 12/70 and I know that the engine was swapped to a '73 sometime before I bought it. So it looks like the jack helps date the engine, if it came from the same car. Edited March 25, 2018 by jwtaylor build date incorrect 1 Link to comment Share on other sites More sharing options...
Terrapin Z Posted March 31, 2018 Share #8 Posted March 31, 2018 Interesting thread @kats I have a pair of wheel stops 0 B and a set of O D The jack in my 70 was a newer one R 1 T I also have a jack from a 3/70 which I can't make out the letters. An interesting observation is the two are different lengths. I was going to swap out my newer jack for the older and it would not fit. Also I was working on my window regulator today and saw it had a date stamp as well 0 4 I IMG_0001.m4v IMG_0001.m4v 1 Link to comment Share on other sites More sharing options...

kats Posted April 23, 2018 Author Share #10 Posted April 23, 2018 (edited) My friend Mr. Shimoura has a super clean genuine Fairlady 240 ZG (9/ 1972), we checked her pockets and there you go, matching numbers jack and choke ! You can see R. I. G. on the jack, “1972 September 7th “ And 2. I. on the choke, “1972. September “ Please note the seat, from September 1972, interior materials were changed to “ flame retardant” , this made the seats looked slightly different from former design and shape.

kats Posted April 23, 2018 Author Share #11 Posted April 23, 2018 Does anyone can sell his/her a set of 9K or 9L or 0A choke ? I am asking this for my Jan 1970 Z432. I found my Z432 has 0G which is Jul 1970. I can sell or trade my 0G chokes. Kats Link to comment Share on other sites More sharing options...
kats Posted April 30, 2018 Author Share #12 Posted April 30, 2018 (edited) Hi ! Here is my Dec 1971 240Z, I am now very for sure our decoding is correct, The tire chockes “ 1 K “ (71 Nov) The jack “ Q. K. C. C “ (. 71 Nov 29th ) What does “ D “ on the wheel nut wrench mean ? I stowed them “ as directed “ into the bin. Tomorrow I will drive this orange 240Z from my mother’s house to my house , 550 miles trip !
