PS: are those aftermarket seats, similar to the ones always for sale on ebay? Those look like they would work, reupholstered in leather, but I'm concerned about head clearance. I tried to use seats from a Mercedes, the seat cushion probably 6"-8" off the floor, and my head stuck above the top of the car several inches - and I'm only 5'-11". Need something that almost puts you sitting right on the floor pan.
