I want to use this rotor on an 1985 Chevy Silverado so that I can use some rims that came off of a S10 I had, I was wondering if the bearings for these rotors are the same bearings as the Silverado rotor would use and ifi would need anything else to use these on my full size truck..The diameters are pretty close to the same...
