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
it seems to clear just fine - the console is a seperate assembly (3 pieces).
I didnt bolt down the seats in thsi pass but they are dropped in. I will remove the bottom track to drop them 4 inches after I do the floor pan and carpet work. They seem to fit the tranny and door sill valley.
