i need to buy new whell nuts for my truck. mine are so rusted and look like you know what. I cant make out the writting on the nut. I know it is a 1976 front housing. my truck is an 85 4x4. I also know the the rear al is not stock but dont know the year. Front is a 10 bolt and the rear is a 12. I think there is a 7 stamped on the side of one of the nut but really cant tell.
