If I were you I would stick to the stock trannys, Your easiest bet is to find a 3 speed heavy duty. That drive shaft should bolt right to it. (correct me if I am wrong, Joe) I have put in transmissions which required me to cut out the trans mount and had to get a drive shaft made, thanks to joe, anyway If I were you stick to the stock trans. I have a few good floor shifters, but I am in indiana.
