Okay I have a 78 Chevy 20 4x4 and when I bought it the muncie sm465 was stuck in third gear so I took it out and got another out of my folks salvage yard that was in an 86 and the outputs are different. I really want to keep my old gear drive transfer case. Does anyone have any helpful hints on how to disassemble these transmissions. I would really appreciate your help thank you.
