I have a buddy who used to own an 03 Mach 1. He's has the stock shifter and stock mufflers laying around and wants to make me a deal on some stuff I have up for trade. I have a 90 GT and have no use for the parts but I'm considering trading for the parts to so I can sell them. Are these parts anything special and do they have much of a market value since they're from a Mach 1?
