If you follow the steps shown for the seat base, then the upright part of the seat will seem easy to cover. It's the same procedure, the wires are just in different places. Once the back was covered, Ambrose installed the new OPG plastic seatbacks-they're available in black, dark blue, dark green, ivy, gold, and red. Holes need to be drilled for the screws. OPG also provided new chrome seatback buttons.
