7 1/4 to 8 3/4 in ‘67 Dart
- shock plates - you can drill your 7.25 plates or get 8.25/8.75 plates
- u-bolts - yep, buy new
- drive shaft - yep, needs to be shorter
- u joints - they make adapting u joints to go from wide to narrow if you end up with that scenario
- Not sure if your 8.75 rear end came with backing plates/drums, but you'll want to check that out
- brake lines are pretty straight forward, but the vent tube may be in a different location so sometimes a longer brake line is needed
- as mentioned above, check the bolt pattern
Thanks 318, I appreciate the comprehensive list. Shock plates and U bolts I’ve purchased. I’ll get a new rear brake line for a 8 3/4 rear. Now for the drive shaft… any idea how much it needs to be shortened by?
