Hi Steve and Karl,
Here you go. I have four C4ZA-5556-S leaf springs. They are dated coded:
No. (1) 141E5 for May 21, 1965
No. (2) 148E5 for May 29, 1965
No. (3) 179E5 for June 28, 1965
No. (4) 295E5 for October 22, 1965
Now for the puzzle you will need to solve. Pairs No. 3 and 4 are on a San Jose k-code fastback project. The springs have been re-arched and restored. The car is a February build and the October 22 date coded single is a decent date code for the car. Of the four, it is the best, but could be a little later.
The No. 3 spring is too early for the car. I'd prefer a trade for a later date code closer to the No. 4 October date code.
The No. 3 June leaf could work for 6S281. The No. 4 leaf could work for 6S406, but a little tight on date code.
The No. 1 and No. 2 springs are too early for the February build K-code, but are a nicely matched set. If I had to pick between matching dates and non-matching date pairs I'd go matching.
The other issue, it is getting cold up here in the Pacific NW and swapping out springs is not going to happen real soon if a swap can be figure out.
What do you think. Can you solve this puzzle?
If I were to end up with a match pair December 1965, restore and ready to install, I'd also be a happy camper. Is there a four way trade out there?
