im sure all the vendors get their its mostly from the same supplier. i have a performanceonline kit and there is no way you can use the original ball bearings on the rotors, just cant do it. if they didnt supply you with tapered style roller bearings you can get them at your local auto supply store. the kit i have uses rotors, bearings and calipers for 1970-1978 camaro.
oh yea, and you're gonna need the bearing adapter that slides onto your original spindle.
hope this helps.
