I started cleaning up the 4 speed trans from my car today and was happy to see most of the original inspection markings still visible under the spray-bomb black paint that I sprayed on it 30+ years ago. I tried to document them as best I could and thought I would post them up for comparison or comment from others. My car is a 64.5, mid April 1964, Dearborn production, D-code, 4 speed, PS, PB, coupe.
Enjoy.
