OK, got all the parts, cleaned and ground ready to install. The angles don't seem to line up. The horizontal trim piece that screws to the trunk hinge panel and the trap door side braces won't lay flat against the mounting holes. The lower horizontal mounting bar that attaches the trap door support sides to the floor looks as if it is dngling in mid air above the trunk floor. I have no prototype next to it to check for accuracy. Any help, tips or clues would GREATLY be appreciated. Thanks yal!
