It's not 1975 anymore....Thrush got bought out, JCWhitney STILL sucks, and American Racing makes the 5-slot mags now. Gabriel still makes Hy-Jackers, but they're BAAD for the car, and out of style like all the other 70s crap. With that said, Hooker makes 71-73 429/460 Mustang headers that are supposed to fit really well, and IIRC, sidepipes are still sold under the Thrush name.
