I thought I would be able to use the stock front seat in my 1949 Buick 2dr Super Sedanet that I chopped 2 1/2". The seat has all new original upholstery that matches the back seat, done by the previous owner. I sit way too high on the stock seat. So I tried cutting down the seat frame, but I could only get 1" without screwing up the adjuster stuff. That helped, but now I am looking through the tinted top part of the windshield, unless I slouch. So now I need to mount the seat with out adjustment or find another seat or some modern bucket seats that will fit. Has anyone done a front seat swap to a 49 or 50 Buick Super or Roadmaster fastback? What seats did you use?
