Sorry that's the best I could offer. The `74 I have has the same panel on the bottom, with the "FORD" stamped in, but nothing on the top of the tailgate like yours. I do know there are two screws holdng the trim on around the latch on mine, but it looks like the top panel covers that trim piece, so you would still need to remove it to get the small piece off around the latch. Just a guess from looking at your pic there.
Hope you get it figured out.
Oh, and PM heep70, he can get it moved (if he doesn't see it).
