After reading this, I am realizing how lucky I was with the '39 top-loader with later gears I put together (can't really say "built") about 25 years ago. I cleaned everything up, used the best parts I had with new synchronizers, gaskets, and bearings and it ended up great. Shifted smoothly and I never broke it with the 276" Merc I had in the car.
I think this is more a reflection on the quality of Ford's parts and manufacturing procedures than my skill as a transmission technician.
Thanks for this thread, Mac. I promise to do better next time.
