** The door jam striker plate in your picture is the same as what is on my 53 Suburban. Most of the after marker vendors will show a different striker plate for a 53. I tried them but they will not work. So I reinstalled the orig. ones that came on the Suburban. I am nearly positive they are the ones that it left the factory with in 1953. Both doors will close and latch with very little effort. I also have a 52 five window 3100 that have the same strikers and both doors close and latch great. When you try to adjust your doors I found it to work a lot better if you adjust the gap in the door and then start with the striker adjustment. Start with the striker plate nearly all the way out {{away from the cab} and move it in very little at a time until you get what your looking for. At least that is what worked for me.
