I'm at work, not able to measure. Also only have a tape measure, not a caliper at home to get accurate measurement. Rotors are for 12mm or 14mm studs. Was there a standard size for the 2000 XLT Lariats? I have my VIN, would that tell me at all? I'd like to get the rotors ordered now, won't see the truck for a few days.

 

Ford changed from 12mm to 14mm in 2000.

Call your local Ford dealership with your VIN handy and they should be able to tell you.
