Are all 80 axles the same?

Clarifying - My 94 with FF rear and no lockers - I can swap a 93 through 97 no locker rear and be good?

I am guessing it is easier to swap a diff than try to rebuild mine - I torched the pinion shaft after the CDL and 7-pin mod.

Next question is - any suggestions where to find one? I am running out of local junk yards to search here in Ohio.

Thanks

Yep, as long as the donor has disc brakes (FF) they're all the same.
 
I am confused about this as well. I know the front e-locked axle & diff need the longer spline inner axle, but what if you are removing an factory locked 80 third and installing another aftermarket internally locked third? Are the rear inner axles all the same on the FF 94-97 80 series?
