'65 Barracuda Trunk Questions: Bumpers, Installation, Alignment?

Just found the old trunk bumpers and the "repro" bumpers from the '64-'66 A Body kit. What the hell, totally wrong orientation for the locating tab and the slot is a different length. This is really pissing me off. Factory bumper bottom (first photo) and right (third photo).
