in 1999 ford went to a metric pattern that only fits newer than 1999 fords---up until that date all 8 lug 3/4 wheels were the same (6.5) but with an alert that GM used a smaller index hole (hub) than dodge/ford/IH---so if you had a stock steel GM wheel it wouldnt go over the hub of your dodge or ford---however all aftermarket wheels used the larger index hole so anyone could mount up....bob
