I'm restoring my '33 PD Rumble Seat Coupe and I can't figure out how to remove the rear spare tire rack from the back of the car. The "pipe" that goes from the rack, through the body, below the rumble seat, disappears between two layers of metal that stretch across the bottom of the car. Does anyone have experience with this? Also, the "pipe" that attaches to the rack has been damaged and welded to the rack. Does anyone know of an available rack that hasn't been damaged?
