So I've got a 95 jimmy blazer 4x2. I was wondering all what I would have to do to stick a 95 chevy 3/4 ton rear axle in it. If I have to I will settle for 1500 axle. I just wanna be able to pull trailers. Current setup she be squatting. Gunna add bags eventually and Currently rebuilding motor. ALSO: Any tricks to getting top 2 bolts out to separate engine from tranny? Thanks.

 

Either of those axles will be 6+ inches wider than your current axle. I would recommend an add a leaf to the rear spring pack. As far as the top 2 bell housing bolts a swivel head ratcheting end wrench helps also put a jack under the trans and unbolt the crossmember and let the tans down a few inches. This will give you more room to get to them.
