Best junkyard upgrade for rear brakes

[Swink]

Hey guys, long time G body owner here, but new poster. I'm finally getting around to upgrading the brakes on my 81 El Camino. I'm going with the Blazer spindle and hub swap for the front. But, I'm also interested in converting the rears to discs. The aftermarket kits are out of my budget, plus I prefer OEM stuff for brakes because I don't always trust the aftermarket guys to do all the R&D to make sure their product is safe. This car is my daily driver, but I'm trying to take it to the next level. No drag or race car, but more just to be able to take to autocross events and have a little more fun. So... long winded way to say, are there any good junkyard swaps for rear brakes? Do you have to swap out the whole axle and diff? I'm not opposed to that, my axle does leak slightly.

The 8.8 is not quite a bolt in deal.....but pretty close. I believe the trick chassis kit in the link below is one of the best kits to swap an 8.8 into a gbody.

Just did this one: wheel cylinders were $10ea and the braces were about $13ea, so about $50 total plus a new set of drill bits and new hardware (actually $100 total)... FML
