My buddy has a 2 wheel drive S10 Blazer he's building up. 355 smallblock on nitrous. we know he's gonna blow up the 7.5 rear axle, just don't know when! We are trying to find a larger axle to stuff into it, without buying a custom narroewd axle? the width is 47" from backing plate to backing plate. I thought maybe an explorer 8.8" might work, but the 1 he measured was 57". wide. Anybody know what might fit width wise? mounting doesn't matter, he has a ladder bar suspension for it.
