dont forget the duct tape...........
the leave it in but remove the wire was were I got involved;
customer says; "we have this switch, and if it is there it has to work so can you remove the switch".
changing the whole cover 1/2 seems a bit extreme, heck I could make a cover/plug out of wood easier than change the cover 1/2. and that may be what happens,,,
wood and glue and chewing gum...
Cant you just leave the switch where it is & just remove a wire of the back to stop it working?
Might be a cheaper / easier solution.
edward t..........you are going to have to replace the whole cover. You shouldn't have an issue finding it at any parts supply house.........PN: 88753-003
