D30/35
60's
Hi9's
Rockwells
 ;D

What size tires do you have?  Stock engine?  Do you wheel or daily drive?  What are your plans for your rig?  Do you have tools?  Can you fab?

Based on your previous posts your best swap is probably just straight replacements with better condition axles.  Decent D30/35's can be found everywhere for cheap.  Kijiji and PNP are your friends.

well I want to do both wheel and daily drive but plans this winter are small block chev and tranny and t/c out of a 1977 blazer engine trans and t/c are all rebuilt just wondering if I could even use the diffs out of it they are 4;56 gears and a set of 39.5 super swampers are coming from ON with a friend so I will be busy

The full size stuff will work but you will have to fabricate/have a shop do a couple things for you such as fabricate  safe crossover steering, and outboard the spring hangers in the front, will also need new driveshafts and mounts for the drivetrain. Be prepared to spend some $$$$
