Can anyone tell me the part number of the front hubs on an escort cosworth and sapphire cosworth are the same? are the hubs the same can they be interchanged? I need one for the track car, at the moment i have 2 different ones on the car the caliper off set is different on them i think one is for an XR4X4

i have been given this number V89BB-3K170-AC

Thanks.
