I love the orig. seat in my '53 3100 but it sat too high for a 6'2" guy and too far forward. I REMOVED the brackets from the top altogether and let the seat rest back against the cab. I glued some foam on the back of the seat to keep it from rattling. The seat is thick enough that my back doesn't come close to the bar. Then, I cut a 1.5" section out of the riser (that attatches to the floor) and welded it back together. I ovaled the holes in the frame to set it as close to the tank as possible and cut 1" off the rear stud risers to drop the back of the seat down. Then, I extended the gas pedal to the right about 4".
AHHHH, at last, I can stretch out and enjoy the ride.
