UH-OH, I think I might have mis-lead you. What I meant that if you change to the 5x4 3/4 bolt pattern, S-10 brakes would work, not that S-10 axle will fit your housing. John Romero has the right idea on axle shafts, though. You could have them re-drilled for the 5x4 3/4 pattern, or possibly get a set for a Chevelle/Camaro from the 70s. I don't know for certain if those will swap directly, but it might be worth looking at. If you could find a late 70s Trans Am many of them had Corvette disks on them with the 5x4 3/4 pattern, those might be somewhat hard to come by though.
