make it even easier,,,
92-94 Gen2 2 LS,,,( not the 92-93 SR . It has 4.88 gears and then you'll have to swap front gears).
3" wider
Disc brakes
LSD , 9" ring, 4.63
bolts right in and you don't need to mess with adding compressor and wiring and switch.
For a SWB all you need is the LSD, unless your doing serious rock crawling.
There's still a 95 SR sitting in a yard near me with fairly low miles on it's locker rear. San Luis Auto Salvage, SLO Town, CA. they'll ship.
