The Ford Barn

Given the gear sets, synchros, detents, etc - in a 39 transmission, I would not have pulled a 39 transmission and installed a 32 transmission (to me, that is going backwards given the end-result).

You will find that NOBODY will guarantee that their rebuilt early Ford trans will NOT pop out of second gear (this is why I build my own!). There are a few tricks/techniques that some of us use on 39 trans to not pop out of second and even with those, after a few thousand miles, the issue tends to want to creep back in when decelerating at higher RPMs.

If it was mine, I'd have the 39 trans rebuilt with the best parts possible - avoiding as many repo parts as possible. Also, I'd have Charlie NY re-bush the second gear to fit YOUR exact mainshaft (this is important for the 2nd gear issue).
