There is a good thread in the '60-'66 section on the Borg Warner option. The thread is here:

http://67-72chevytrucks.com/vboard/s...=313886&page=4

I learned a lot about wiring, etc. from that thread. I installed a Borg Warner OD for the same reasons as you in my '59 w/235. The best thing to me is everything bolts up to your stock stuff, no driveshaft mods, the 3 speed linkage hooks right up, input shaft, etc. The one glitch I had was I had to install Helicoils in the ears on the 2nd trans I got to take the bolts from inside the bell housing. This was because it was out of a car instead of a truck, that's my understanding at least.

I bought a rebuilt unit from Garage Motorsports in Vancouver, WA. It wasn't cheap, oh well.

The other option is the later model 5 speed out of 80's GM cars. There is a couple of good writes up on that too, a bit more involved, but people have good results. I'll try and dig up a link on that later.

The link is: https://lugnutz65chevystepside.weebl...info-page.html

This is for the T5 trans set up, a lot of good info there.
