Been in search of inexpensive rear disc conversion

[BHyatt]

I have been searching around for the least expensive conversion from rear drum brakes to rear disc brakes that I can find. I found some relatively inexpensive brackets to mount front rotors on the rear from Ebay. I then found them cheaper on Speedway Motors.com. The brackets from Speedway may have sealed the deal for me though when I noticed a bracket for 78-up Metric Calipers. This sent me back to the Junkyard where I found a rear wheel drive 1979 Cadillac Seville with calipers which include built in emergency brakes.

When I went back and removed the calipers I noticed that the factory brackets for these calipers along with the backing plate bolt onto the end of the rear differential. I now believe I will go back and remove the factory bracket and affix it to my rear-end rather than purchase an aftermarket bracket. I need to measure the rotor too see if it can be found with the proper bolt-pattern or just use the ones from the Cadillac and have them re-drilled.

Anyone have any thoughts on this idea?
