i am looking for an 89 through 91 formula it can be any color. i want a 350 with t-tops

I have an 89 Pontiac Formula 350 Firebird, new: 5.7L engine, trans, exhaust, headers, sound system. We put in custom twin superchargers, I'm in the Chicago area and am looking for about $5200. The interior is great and the outside has just two small rust spots on the doors. Let me know if you are interested- I have pix and receipts for everything.
