Ok. After much thinking, I think I've come up with a solution to the trunk latch striker. I've attached a sketch of my idea. The striker would be made from either .080 or .125 mild steel and made in three pieces. The center piece would be notched and then bent 90 deg at each end. The two end pieces would be welded to the center piece, and slotted holes added for adjustment. Height could be managed with shim washers. It would be mounted to the frame with #6 sheet metal screws to the frame. I would still have to clearance the body and the trunkpan.
the latch arm would swing down thru the notch and push against the plate creating sufficient tension to keep the trunk lid closed
