I did ring and pinion swaps in my truck in the late 80's. I think I broke the 12 bolt in some way 8 or 9 times? My truck has a semi-float 14 bolt from an '86 3/4 ton Suburban and we just pulled a set of 3.73 geared axles from an '84 Sub for my kids project. Both of the 9.5" axles have Gov-Locks in them and we are putting a TransAm clutch posi in the front of his.


I can't see spending $1000 to re-gear your axles and less it is REALLY important to you. But you can probably find a beater Suburban and pull the 8 lug axles from it. (I paid $300 for the 4.10 equipped truck that was equipped with HD towing an TH400. The 3.73 truck had a TH700R4 and was $200.)

As you can see, if it were mine I would also be looking for a strength upgrade at same time.
