(3500 plus shipping to MI) so I found the needed OEM adaptor and a 700R4 and made the swap. I have no clue how you might go the route of a manual and make it OD. First thing is to figure our what you have.. IF you're on Facebook, send me a friend request and I can send you pictures of my various swaps (rea gears, trans, intake, carb, etc.
I took my driveshaft up to shop and they said somebody stuck a small shaft into a larger one and welded it.........So now I'm gonna have to buy a rear end, and drive shaft. Have any ideas on what can bolt up with 3.20ish gears? New ones are pretty expensive, any suggestions?
