After welding the passenger side door bars, my old 88 Si passenger seat doesn't fit. The coil spring mechanism on the outside of the seat hits the bar (by about 1/2 inches). I took the plastic cover off, but still no good. I'm wondering if the non-Si seats are any smaller, or if any other seats might fit in place of this Si seat.

 

Nobody knows?
