By the way...there were never vehicles built "with left over parts." The occasional seat, steering wheel, brake parts, and even engines--as in the case of '65 Impalas built with 409s until the supply was exhausted--but they didn't build a complete vehicle out of "left over parts." Fenders, doors, windshields etc. would have gone in the body shop supply. It's not like Chevrolet was hand crafting trucks and had enough parts left over to build one more. They're trucks, not GT40s and Shelby AC Cobras.
