Ken--
I'd appreciate your photo. I think I must be missing the interior piece on which the assembly pivots. Have no idea what this looks like or where it attaches. I have the lever which attaches with two screws to the top of the curved bracket which is spot welded to the sheet metal flap. It seems like there has to be a third piece, the one I probably flung into the bushes two years ago when I took the cab apart.
