Seat conundrum
Haven't done it personally, but I have seen a number of A bodies that use the Smittybuilt low back Jeep buckets, because they look so much like the A100 seats used in the LO/BO hemi cars. Pretty darned inexpensive, too. They also have high back versions with headrests if that's what blows your skirt up. Both adaptable to darned near anything.
