Does anyone know if the flange size and centerhole are the same from a 1500 to a 2500 2wd on the front steering knuckle? I have an 8 bolt axle on the rear now and would like to have 8 on the front also. the flanges are both 3 bolt, but short of ordering one to compare sizes I dont know how to find out. Could someone with a 3rd gen 2500 2wd measure the centerhole where the bearing fits and the spacing of the three mounting bolts on their hub. It would be much appreciated.
