94-96 impala ss reear under mine. 3.5" shorter than a stock c1500 rear. should have discs and limited slip.

you can also use a caprice 9c1 rear. it typically has 11" drums. the widths are the same(or very close).

buick roadmaster/ caprice wagon rears would prolly work, but i beleive theyre slighty wider.

you will get a 5x5 bolt pattern from any 91-96 impala/caprice.

my only suggestion would be to press out the wheel studs, as theyre 12mm and your truck likely has 14mm studs up front. this way, all your lugnuts match.

hey man.. mine is a 95 model. it has the Kelsey Hayes ABS brake proprtioning system; it essentially automatically adjusts to different brake pressures. it aint perfect, but hey, it works. ive also got a hydroboost setup on the truck from a 3500 model.

together, they make for awesome brake pressure, and a really firm pedal feel.

in a perfect world, i would do away with all the abs crap and go with a manual brake proprtioning valve. www.waylayedinc.com has some good stuff... if i ever get motivated, i'll buy one of these for mine...

being that yours is a 94, it should be pre-abs/ kelsey hayes unit, and one of these valves should do what ya need to do! good luck and let us know how it turns out!
