I just replaced the bushings on the driver's seat of my 2001 Z3 and installed the Seat Mod Tilt Kit from Street Driven Industries. I reinstalled the seat, tightened the rear bolts, then powered the seat backward and tightened the front bolts. Now the seat won't go forward and I can't access the rear bolts to tilt or remove the seat to see what the problem is. Any Advice?
