I know a guy locally possibly selling a 200r4 or a 700r4, If the price is right Ill take either. Its on an elcamino and I have a 78 Malibu my question is will the driveshaft work? We both have the 7.5 rear so thats the same. IF the drive shaft works I can get everything and itll be a quick easy swap from my 350 trans.
