In the recent two seater thread, someone mentioned taking an inch height out of the seat track riser. Can they provide the low down on this before I take my car apart? Do the tracks bolt to the seat? Did you use a saw to cut the legs then slide the pieces up and weld them on both sides? Did the plastic feet covers still work? Anything special I should know? I repadded the driver's seat and am short on headroom. The old padding was cardboard and carpet.
