not the same rearend, not a compatible swap, check your spider gear shaft they had a bad wear and breakage problem.

YES they are both 7.5 rears but gm. did a redesign in 88 that changed the size and number of axle splines and side gears , axles are not interchangable

I think it came out of an 86, not sure. any sugestions on how to tell. Thanks

the only way to tell is to pull the rear cover compare the two, if they are the same you are in luck.
