Just a quick update to show how the rear window turned out with the boarder black added, and a pic of the rear latching mechanism on the rear half of the trunk lid. When the T-handle is rotated, the rods extend and pass through holes in the body flange surrounding the trunk opening. Works really well! I used some heim joints left over from my IDF linkage along with some ¼” aluminum rod, then made up some cardboard patterns for the center anchoring bracket and propeller (for lack of a better term), and then had it fabricated out of aluminum sheet.
