Kinda. They need to be modified. I am pretty left field, so buckle in for the oddest way to save money on your rear axle you've seen lately
.
I am planning on doing another 8.5 10 bolt for wagon this summer.
I did a zr2 s10 8.6 rear which works but is too wide. C5 wheels solved that. Long term i want to go back to 15" wheels with 4" BS so I am going to cut the rear I built (below) to stock G width and upgrade axles since I shattered a stock 30 spline axle. I am a special case though (500+ hp stick blown LS2)

My next build is to take the stock 7.5 g body rear and cut the tubes half way between the housing and the LCA bracket and remove the whole 7.5 center section. I have a spare 8.5 center section from a zr2 on hand so I am going to cut the tubes in a similar place and butt weld the 7.5 axles to the 8.5 carrier. Then I will bolt the plate I make (below) and bolt to the 8.5 carrier.
I will end up with
stock 7.5 rear- Free
8.6 out of a zr2 S10, 1500 silverado, or a
B body (A
b body posi rear is the best since you can keep the stock carrier in place since they have a clutch posi stock)- $150
Sandwich plate UCA mounts- lots of my time but if I ever get around to making them like I said 2 years ago- $175-200
Moser 30 spline GN width 8.5 axles from summit-$250
Yukon clutch 30 spline carrier (optional for
B body but i would do it for a gov lock, i grenaded mine) $300
If you "buy" the setup I will end up with it's $900 plus time, which is roughly what a GN rear costs but you have upgraded axles. It's about 600 bucks less than most 9" new I have seen by the time you end up with a carrier worth a damn.
