Any short tailshaft TH350 is a bolt-in (and is a popular replacement for the Junkaway). There are two issues you'll have. First, your stock shift quadrant will only have two detents for forward gears, so you'll only be able to manually access drive and second, not first. Second, the TH350 uses a cable kickdown. You'll need to get the bracket and cable from a mid-70s Olds to connect the cable to your carb throttle lever.
