I just bought a polished Centerline wheel off CL seller said its a fatboy wheel. it has a 3/4" bearings w/a 2 1/4" flanges for sprocket and rotor. Are the flanges the same size for both sprocket & rotor ? I have a 92 and wont fit my sprocket and rotor. flange is too big on the wheel. Any help what years does this wheel fit.?
