I'v seen this on CL for a while and it sound like a real good deal, I have a 68 camaro with drum brakes all around and wanted to do an LS1 brake swap but these C5 fronts are cheaper and larger then the LS1 camaro fronts i still plan on runing LS1 rear disc brakes w/ the e-brake.

My question is, I call the guy and he said "it fits both disc and drums", but from what i have read the HUBS need to be muchined down to fit the rotor, do u guys think i should buy the kit any ways and at worst all i would have to do is muchine my hubs?
