called napa today (we know the guy that runs it) and there is a 55 dollar core charge per caliper. he doesnt think my calipers will work for it since mine are v6 calipers. out of curiousity, what years/models had the big brakes? i know 01 bullitt, 03/04 mach 1, 99/01 cobra (assuming 99 did too), 03/04 cobra. anymore? i might order from something besides a cobra, i dont want it to say that on the caliper. also, diller, what rotors did you buy?
