OK, so you actually have the seat sitting on the floorpan? I sandwiched the floorpan between 2 pieces of steel but mad seat mount brackets under the seat that are adjustable for tilt.
Are stock factory seat adjusters legal? I've had a car with a poly seat that had the poly seat bolted to the adjusters.
