[CHANMADD]

So I used a threaded rod through the trunk floor...washers either side and being a threaded rod I can adjust it infinitely ,on the other end ..the end that latches I welded a single link of chain......the chain link if you look at the latching lever on the latch it has a cutout that fits around the link. If you adjust it right as you turn the handle it will compress the trunk against the rubber seal and then pop slightly up. The notch in the lever keeps it from opening..but you must have the pressure from the rubber seal to keep it tight. ;......I bent the threaded rod inside the trunk to follow the contour....it works great .
