Our 67-72 C10 aluminum tailgate is made using 1/8” 5052 aluminum. It comes complete with brackets to bolt in place. Note, this tailgate does not hinge at the bottom or open and close like the stock tailgate, this is an outer skin that bolts in place of the stock tailgate. Expect a weight savings of 36 lbs over the stock steel tailgate. These tailgates are made to order, with a 4-6 week lead time.
