Which Calipers do I need?

I have a 1988 Formula and I need new front brake calipers. I went to rockauto and find two kinds. ones that say "except performance package" and ones that don't. I don't know if I have this performance package or not. How do I know which calipers I need?

You'll have standard iron Delco-Moraine calipers (non-performance). The performance package has the dual piston alum PBR calipers found on 1LE cars.
