i installed mine like the directions from Steele showed, but I had to call and find out what they were, their not easy to understand on the little scrap of paper instructions. The top goes on the body running down to the hinge's, the other piece goes on the door and runs to bottom of door where the short curved piece goes at bottom of door. hope I didn't confuse you but that what they told me and that's the way I installed mine.Mine is a 41 Business Coupe.
