Oops sorry for the typo on the 64 ot 74 deal. I meant the 1974 GTO was like a NOVA chassis.
The drive shaft from any other GM 10 bolt(7.5 8.2 8.2 BOP) or 12 bolt (chevy or Olds) will need a 3/4" (about) cutting /shortening to make the 10 bolt 8.5 rear end swap fit on the drive line.
The chevy to BOP and vise versa... conversion joint I think is neapco 3310-3 If memory serves me right. Jim
