Here are some markings we found on the car...
What is the cars VIN or at least Month, year and assembly plant - please
Without that ... well you know
Guessing 65-66 San Jose production C or A code conv
Split the thread since it was going (with your post) in a different direction with a different car
Haven't seen this before and it's not on my 65 Dearborn car. How common was this and how was it done on a black interior?
Haven't typically found these (rear of car, seats, hoods.....) on 65-66 Dearborn cars, seats and other pieces were marked differently (at the subassembly points) there than at San Jose. Seems, from the original pictures of the line they attached buildsheets front and back (writing the second rotation number on the front crossmember) rather than writing on the body
