i cant seem to find the correct long wheel stud for a 71 b body disc brake hub/rotor. i ordered a moroso set but the knurl does not go through the rotor far enough to engage the hub. i have long studs in another 71 but as i recall the hub and rotor was all 1 piece ( i could be wrong ) . i see arp sels a stud that looks like it may work but its listed for early ford disc brakes . the part number for that is 100-7707.
