4th gen brake calipers on a 3rd gen?

Does anyone know if there are any major problems with using 4th gen brake calipers on my 3rd gen?
I saw some nice red "Trans Am" calipers at a recent car show, and was wondering if there are "Firebird" or "Formula" calipers made. I sure would like a set for my 89.

All those are is just painted calipers with a decal over it. I'm sure you could do that to the current set you have now. Just takes a little cleaning, some paint (which you can find at any auto parts store) and a caliper decal which if you google, you'll easily come across.

Sweet, thanks for the info!
