If you do NOT stay original, expect to lose 99percent of your investment in reupholstering if you ever sell the car. Your taste and the next owners will almost never match. Ditto with the 76. Unless you pay a bundle to to get rid of ALL of the yellow on the firewall, door jambs, etc, youd be better off keeping the yellow. I had a 76 Fleetwood in your combination. It was a stunning car. Black top, black dElegance velour interior and the "whatever they called it" Ivory body. (Im too lazy to run upstairs and check the color chart...)
