Hi again from Germany,
I'm working on the 4-speed crashbox, unfortunately the thread in the rear end of the mainshaft has a slight damage. The first few threads are worn but there is enough thread length to use a longer screw. I cannot find the matching screw and so i cannot measure, how many TPI the screw should have. The old online chevy manuals database shows this:

Hmm, bad quality, but the thread sizes vary between 20 or 24 TPI depending on truck type. What thread size applies to my 1946 half ton truck?
Thanks in advance again for your help!
Sven
