With you in NC and not sure had to look. I built a 66 Nova that had junkyard brakes built to fit. Had Aluminum Fiero on the front with Pinto rotors and for the life of me can not remember what was on the rear.

If you keep those calipers on the car I'd suggest swapping them side to side. From the pics it looks like the bleeders are on the bottom that will make it very hard to get all of the air out.
If you have some time, a good wholesale auto parts store may be able to send them out for rebuild & return. The rebuilder can probably identify them for you for the future.

Before you spend the time and money to upgrade the calipers swap them side to side and get the bleeders on top.
I don't want to sound rude but it honestly took me a few minutes on Google to find out what calipers you had. If you can't take the time to find out what you have and what you can use you might need more than Internet help.
My intentions was to replace them since I had replaced the front ones.. I just didn't know what ones they were. So since I was going to replace them I thought maybe a new version would be good at this time...

The rears look like fronts because they are same casting shape, same bolt pattern and use the same pads as fronts.
When you purchase GM Front calipers, you Do Not want the Low Drag models that came with many cars of that aira. Low Drag calipers will have the piston falling back slightly when the brakes are released. They also required a special master cylinder that delivers the added fluid to compress front brakes without using more brake pedal to activate. This Low Drag model is not what you want on a manual master cylinder car. It uses more pedal to collapse.
When looking at the caliper you can’t determine if it’s low drag or not. I’ve read that installing a block of wood in caliper to stop piston travel, and compressed air to force the piston out, one can determine if the piston returns slightly when air is removed. When you purchase re-man calipers (this is everything from Autozone and others) you won’t know what you’re getting. If you have low drag on a car it’s easy to determine. With the wheel off the ground, step on brake and then release. The wheel will spin effortlessly and you can wiggle the inner brake pad because they’ll be a .020” or larger gap.
I put new stock style metric calipers on the front of my 83 Camaro when one failed and ordered AFCO Metric GM Calipers 6635003/4 AFCO at Summit that are new castings and non-low drag models. Made in China.
