i know its been covered a million times.... but i couldnt find the info i needed. the product review is for a semi floater axle, so it's a bit different... sooo.... i can use 76-78 caddy elderado rear calipers or chevy front calipers? what years? 1/2 ton or 3/4? chevy front rotors? what years? 1/2 or 3/4? what kinda prices do these normally run at the parts house? just trying to get an idea of what i'm getting myself into. my 10 bolt has rear calipers & caliper brackets from an 84-86 mustang SVO (has ebrake) i might see if i can make those work since i already have them..... and, it has ifs front rotors.
