Hi Craig -- interesting setups, etc. A good friend of mine, who is extremely active with the current new-gen SCCA T/A classes, as well as a co-owner of a T/A team, and of the SCCA marketing rights for the T/A new-gen series, has recently acquired a surplus of Dodge Challenger T/A PRO racing parts -- suspension, bodies, radiators, brakes, engines, etc. He intends to put it on the market for sale, very soon.
IF you're interested, send me a PM... or anyone else who may be interested. I'm pretty sure the parts are close to Chicago-area.
