If you have a torch set and a welder, that's a good start. If you can fabricate stuff, and have excellent mechanical ability, it's not that difficult, and has its advantages over the stock housing. If none of those things are you, just get a good stock posi unit, put some 3:73s in that baby, and get on down the road ! 😀 .............mickey-d :lol:
there's no strength difference between a 7.5 S-10 rear and a g-rear. if you're looking for cheap improvement, either find a GN 8.5in rear (best) or a late (86-88?) monte SS 7.625in rear. both of these will need the entire housing, but are direct bolt ons. btw, they came w and w/out posi, so check first.

If you are fund limited he is right...look at some of the sigs on this site a lot of people get away with it for a while. The 7.5 is by far a weak link but there are upgrades you can do. You can buy stronger axles for the 7.5. This is a very easy posi unit to install http://www.summitracing.com/parts/PWT-1930-LR/. However if you do go to a posi with the 7.5 stay away from sticky tires. As far as the question you asked lol I am pretty sure the s10 unit will work as long as it is not a 28 spline unit.....don't worry someone will correct me if i am wrong about that, but i am pretty sure it's a go
