Rear end mounting question

junkyards full of mid 90s jeeps with suregrip diffs, and good gear ratios to for cheap!
This has probably been answered a million times by now but hey, I just joined FABO...
I will be very grateful for some intel on what Jeep differentials will be compatible with the 7 1/4 in my 73 Dart. Or send me to a link. I need to rebuild my 7 1/4 pretty much immediately.
Thanks!

Maybe you can disregard. After thinking about it, I believe the Jeeps are all 8 1/4.
