10 bolts, 6 lug to 5 lug, and 28 to 30 spline
Okay, asking this for Sparty (I'm bored and he's not online, so I'm asking[img]images/graemlins/wink.gif[/img]). He has a 94 Chevy C1500 (yep, 2wd) he's got lifted a little, but the 3.42's in the current rear are barely cutting it with the 31's he has now. This summer he's going 33's if he can, so we're looking at cheap(er) ways of getting him a 3.73 or 4.10 gear ratio.
One thought is just another 10 bolt with the desired ratio already in them, so that saves on the install cost. If it's a 4x4 axle with 6 lugs and 30 splines, can we just swap the axle shafts and drums from his current axle to keep his 5 lug pattern? Ditto for a 12 bolt if we get a 2wd truck 12 bolt to swap with?
If we find a 80's 10 bolt with the right ratios, but 28 spline shafts, we'd be looking at tearing the diff apart and putting in his carrier, gears, and shafts, right?
