[DSYenko]

I dont think anyone is ganging up on me but i do think back a few years ago when i drug home a pretty rough 81 Camaro out of a towing yard in California.That was when i located this site and had several nay sayers as it had a early build date ect ect.Come to find out it wasnt just a Yenko car it was one of the 2 or 3 prototype of the 18 Yenko Turbo Z cars.I learned long ago with this car stuff never say never.Id like an expert opinion on that front pad and broach marks and the stampings. Thanks again guys
