Huston 54, Thanks for your input on this, I wanted to be sure you knew I was considering useing a 1976 trans am sub , not a pickup frame, is there alot of difference between the widths of a 68 camaro sub and a 76 firebired sub? The firebird sub is alot better as in it already has disc brakes and has a stiffer spring rate thanks again for everyones time
