The lugnuts on my 86 TC seem like they dont have enough of a seat. It looks like the sides of the lugs are about to eat into the rim. Im thinking that they arent the orginial lugs.
Can a lug have to much of a seat? Maybe mine are fine, but I would like to swap them out just for the peace of mind.
What size thread is stock?
My spare lug nut is 1/2" x 20R and takes a 13/16" socket and is 5/8" high. Got that off the bubble pack card.
