Has anyone installed more modern bucket seats in their A Body??

Going back to the Lo/Hi back issue. If you want the low back, but with power, you might scour classic Mercedes forums or some such place. cars like that are about all I can think of that would be low back and power.
I went with the ProCar seats. So far fit & finish seem fine, but actual usage is still yet to be determined, though I've heard good things. Bigger range of slide & manual recline.
Many modern car seats need a flat floor. The big hump where the bench seat mounts might get in the way. I flat floored mine since it was all apart, just in case in the future I want to go a different route.
