Resto Your car is not an LDO car. But it does have factory bucket seats. Which I think look better than the LDO seats. You should be glad your car is not an LDO, that would just mean more work for you to get it to the way you want it, More chrome trim, rivets, and holes to deal with. Been there done that, my car was origninally an LDO car.
I'm wondering if a set of LDO headrests would work with the standard bench seat? The stock bench seat headrests don't go up high enough for me and it looks like the LDO ones are taller.
