72 Demon seat backs?
It is just a sheet of vinyl on the back sides. Not sure of what year car yours is, but the front could be all vinyl or have fabric inserts on them. Here are photos of mine from a local upholstery shop, they are for a 71 demon. The same year seat for a swinger has all vinyl. I'm sure you could call a local upholstery guy to fix it up.
As for the honda seats, you'll probably just have to fabricate some brackets to adapt to the floor for a good height that works for ya. I don't see why they won't work. Dye them to match the rest of the interior?
