In buying new rotors online I am presented with an option of 12 or 14mm lug size. Is there a standard size or do i need to measure (the truck is at home and im at work). Its a 2002 4.6L V8XLT extended cab (not the full doors in the back). Thanks in advance. You guys are a wealth of info.

 

1997 through mid 2000 used 12mm. Starting in mid 2000, they went to 14mm, so you should have 14mm holes.

 

thanks matt
