74 C10 rear end interchange

[oldearl]

Hello All, it's been a while since I logged in here. Lots of great information when I use the search. All of your expertise is very much appreciated.
I am looking to find out what other square body year rear ends fit a 1974 C10 long bed ? Is it 73 to 79 without changing anything ?
It seems the poor old girl is asking for more money to be put into her.
The issue is when I put the auto transmission in gear she sorta locks up until I give her more throttle, it makes a popping noise then moves very slowly . I did jack up the rear so that the wheels were off the ground. I can spin both wheels with the trans in park.
Thanks in advance
Old Earl

If you're going like for like axle and doing the whole axle, I believe all the square body rear ends are set up the same.

All of the 1/2 ton square-body rear axles should bolt right in, but the driveshaft yoke may be different. Not a problem if you have a local place that can change it if necessary.
