Were the PBR aluminum rear calipers used on a 89' the same ones used on on 93-97 Camaros?

Yes...with the exception of that weight thingy and the minor difference in the e-brake bracket, they're the same.

Not to make any trouble, but I went through this a few weeks ago and found that the rotors and other parts for third and fourth gens have different part numbers. I'm not sure just how different the these parts are from each other or if you can swap third and fourth gen stuff.

I think you have to use 3rdgen backing plates from what I've gathered reading here. The calipers themselves will bolt right up.

You can also use 4th gen backing plates and they will work, too. The calipers are identical with the exception of the big weight and the e-brake bracket that holds it. Same thing...
Even though the part numbers are different, you can use 4th gen ('93-97) rear rotors too, they're the same thickness.
If you have relocation brackets and use 4th gen calipers, you will HAVE to remove the weight and cut the bolt that holds it off or it will interfere with your relo brackets.
