Factory BBP on 7.25 axle

When I switched to BBP front discs on my '71 Scamp, my donor car was a '75 4-door Dart Custom, with a /6. To keep the same 5x4.5 BP at all 4 wheels, I also swapped out the 7.25 rear ends. I didn't notice any differences at the time. I compared them side by side and didn't see anything to cause concern. Not that I can remember anyways. Had there been something really off I'd think I'd recall. (This was done 8-9 years ago.) To this day the Scamp is running with the Dart Custom front brakes and 7.25 rear. I kept the same drive shaft though. Wish now I'd taken pictures of both rear axles side by side, for reference.

I put my Scamp's SBP front drums and 7.25 on the Dart Custom and sold it. The guy who bought it was going to use it for more parts, but he told me later on he ended up driving it for a while. So it seems any differences are minimal between 68-72 and 73-up a-bodies as far as these parts go. EDIT: I should clarify that the differences are minimal as to affecting their usage in a swap. Obviously they are "different".

As far as u-bolts, during the swap I twisted the threaded end off one while unscrewing some very rusted nuts. I don't recall now which one, as I reused two good u-bolts for my Scamp and just put the Dart back together as best I could with the one broken u-bolt. I certainly don't remember them being different sizes. Again I wish I'd taken pictures for reference.
