The one's I like are flat like in the 60's. The side flairs interfere with steering, getting in and out of a 1974 cuda is a chore due to low head room, windows that curve in, slammed low rider rocker panels. Those cheek bolsters will trap your ass like a saddle. I like to move around and find a different posture and flatter seats let me lean to get circulation back. On a long trip you won't like the racing posture anyway. Get two sets, for the price of new foam and labor to recover the originals. I hate the stock 1974 barracuda buckets more than any other year, mopar went cheap on the seats to cost compensate for the seat belt switches, they offered no seat option. No hard seat backing just vinyl, and thin foam, with less wire support, but they are bullet proof with the high steel support inside the back. The 1968 barracuda had flat low white bucket bench seats with ribs spaced like these, that's why! They fit either car with a change of floor adapter and use their own included sliders. Get what you like.
