X2 on the caddy seats
first pic is from a 76 coupe de ville, 2nd from a 75 de ville conv't. 1974 seats have narrow pleats, and are totally different. I would say yours are from a 76, and they do make factory reupholstery kits for those if you like them. OR you could pimp them out in fur like the guy has near the start of Magnum Force (Dirty Harry movie) LOL
