-Ok I built a new doubler and cover plate - wasnt' happy with the 1/4 turn fastener edge distance on the cover plate - mostly for costmetic reasons. -First cover plate got eaten by the drill press - darn fly cutter. Second one came out perfect. -Match drilled the new doubler using the old one -Layed out the 1/4 turn fastener location. -Layed out the 1/4 turn fastener receivers onto the doubler.
