I hope this information helps someone.

I transferred a 1954 sm 420 into my 48 1/2 ton chevy. I like a floor shift and it works fine. But, I wanted a backup lamp for safety and found a 67 sm 420 lid. It fits fine but will slip out of 3rd. I called Novak for help and advice. They said the shift forks are different and I need to switch the 3/4 forks from my 54 lid into the 67 lid inorder for it to work correctly. Their rebuild kits are different for the various years. Kits come for years 47-53, 54-63, and 64-67.
