Anyone have any luck finding a good replacement driver's seat that mounts to the flat floor on many of our buses? I was hoping to upgrade my very uncomfortable 'metal frame with foam over plywood' that they call a seat with something a bit nicer. Possibly a seat from an Cadillac Escalade or a Lincoln Navigator

or whatever I may find at the local car graveyard. I also want to replace the steering wheel since it is so big it hits my legs when I am seated and I barely have enough room for my knees when I operate the pedals, and that's with the seat as low and as far back as it goes!
