I have a 70 mc and I'm getting a doner 2000 chevy 1500 2wd auto trans. Will the rear end and 4l60e swap into my 70? Obviously I'll have to relocate the spring hangers on the rear end and alter the driveshaft length. I assume I'm going to have to move the trans mount as well hur is there anything else I'm missing? Or is this swap a giant pain and not worth it?
