Does anybody know if a set of 16 inch American racing wheels off of a 1994 4w/d F-350 will fit my 2000 F-250 4w/d Superduty ? I think the wheel stud size is different, I'm not sure.. Is the back spacing different also.

 

No. Super Duties have a different lug pattern (8 on 170mm). No other truck uses that pattern. 99-04 wheels have less backspace than 05-11 wheels.
