Hi Mark, What I have or had originally is just like your picture. I did some research and discovered that the replacement door I have for that side must be from a 53 model that used some sort of conduit as it has a round hole versus the square one. I try and get a picture on Monday when I'm back at the barn. I guess my "fix" will be to cut a square hole and mount the contact plate with sheet metal screws. As a side note I'm still looking for my lower rubber bumper! Thanks for the pic and the response.
