The left side rail that is attached between the seat bottom and the sliding mechanism has physically broken. The part is no longer made. I can not find any instructions to remove the height adjustment knob so I can remove the side panel and get to the rail. The 1997 does not seem to have a removable center section on the knob so I can remove it. I installed a 1998 drivers seat, but the seat belt receiver for the bracket is larger for the 1998, and my seat belt will not latch. Bottom line, I need to either weld/attempt to fix the rail, or change the seat belt receiver from my 1997. I still need to know how to remove all the panels and the adjustment knob. I also would like to change the upholstery.
