I've got a couple of those if @Dana67Dart needs?
The 67-9 cuda fastback plastic bulb holder for courtesy lights. They area sold by MH, but cost $10 each. I ordered 4 and by the time shipping etc. Damn close to $100 Cdn lol.
The little plugs that go into the hole below the wing vents. I forget his name now, but a guy in Florida made 3 of them for me, 3-D printer. The cap plugs that are sold to replace them are terrible. Bet that a lot of people could use them.
