I recently bought a 1997 Firebird and with the stock seats I don't fit very well in it unless I take the roof off and still the seat bolsters are digging into my back and my legs are hitting the wheel. I'm a big guy so I know I'm not gonna fit perfectly in there ever but does anyone know if its possible to move the seats farther back then the sliding rails or if there's a seat I couls swap in that I can put right on the floor and far back that's good for big guys thanks
