We (RS Performance) have just finished the first set of billet hinges designed specifically for the 66-67 A-Body. They are designed to bolt directly up as a stock hinge would with out any modification. The proto-typing is completed and we are looking to go into production on the hinges in the begining of January. They should be completed and the first batch ready for shipping towards the middle of February. Check back on our web site
