I had used cadillac eldorado rear calipers with integral parking brake on a 7.5 inch wheel. Was a pretty easy mod. I have to get the pictures off of my cardomain (crap site) to show the orientation, I don't really remember.

I mounted these facing forward, stock width rear, lowered, with the clearance issues
Tried with it facing the rear, but the shocks were in the way.

Those brackets look like they're from a late 80's F body rear set up. The Caddy brackets don't have the offset bend.

Anibus, you are correct sir. I wanted to put a follow on post.
The calipers are from a caddy Eldorado since there is a left and right. The brackets are 3rd gen F-body, with one flipped around. f-bodies had the calipers position one side front, the other rear. I had to turn the axles down a bit to fit in the rotor hat.
As the pictures show, they fit in the rim, and on a lowered car with no frame contact. Just figured I'd share for another option.

I understand what folks are saying relative to the caliper hitting the frame and now I know why. If your car is lowered more than an inch or two and the caliper brackets are installed with the orientation GM intended them to be in (Forward Facing Calipers) frame clearance may be an issue. LS1 Camaro's have forward mounted rear calipers and thus the eBrake setup is designed to work that way. Swapping from one side to the other makes the eBrake triggers face the rear, the wrong way and presents an entirely different problem.
If you look at the best balanced cars, they typically have the calipers facing the middle of the car i.e. front caliper faces rearward and rear caliper faces forward. This puts the weight in the middle of the chassis and not at the ends where it turns into unsprung weight. Not that I'm building a Ferrari here but I'd really like to use the brakes as they were intended to assure the car stops with my big *ss in it.
Uncle, ... I give, I have the same issue and am looking for a way to resolve it.
1) Cut the inner most cooling fins off of the calipers (produces an additional .500 clearance) probably not worth the exercise.
2) Modify the section of the frame where the caliper bottoms out.
3) Do nothing and hope the rear coil over shocks can make it ride right and not over compress.
