Not sure on which goes where on the door frame. I did look at the catalog and see that one of the conical bumpers is definitely larger around and taller than the other. One way to figure placement out is to get a chunk of clay or similar compressible stuff, form a ball and stick in each corner bumper spot. Gently close the door until it is flush with the cab edge, then open back up and see which glob got crushed more than the other. You should be able to judge which spot gets the larger and which gets the smaller bumper then. smile
