I recently purchased cp30101 drop spindles for my 64 impala. I also purchased the 5870dbk brackets to use s-10 type single piston calipers and 11 inch rotors. The rotors I purchased from cpp, #ar-8208e will not fit. the a-6 inner bearing fits the knuckle, but the rotor contacts the knuckle befor the inner bearing is all the way on the spindle. The grease seals that came with these rotors are also too large. The outer bearing is too large for the sindle as well. Is it possible I have received the wrong spindles?? Or can 11" rotors not be used with this spindle? Has anyone else run into this?
