I tried searching but didn't find much. Is there a cut off date or any way of knowing if you have 12 or 14mm studs in the rear rotors short of measuring? I need new rear rotors for a 2000 F-150 XLT SuperCab 4x4 w/ 5.4. No tow package or Payload package.
Stamped on the wheel near the lug nuts is a code with the wheel size, etc.....the last digits are 14 if 14mm. The lug nuts themselves have "100" stamped on them if 12mm. and "150" stamped on them if 14mm.
