I'm going to try add a link here of one "laid out" which is for my 52. Those long threaded rods had a little cupped rubber type "bushing" but I have not found any.....but some may be "carved" out of a piece of rubber like a shock rubber...just saying.
The top and bottom latch, on mine, require some attention big time as they were pretty deranged but they can be fixed.

There is also a rubber bumper that goes on the left bottom door. I made my own but later found it at Steele Rubber but simply will not pay the "asking price".
One of the links under my signature line is the link to my Google account for the panel. There are a couple more pictures of the "linkage" if you want to look. The rods can be make if you have one. A machine shop can turn you one out pretty quick out of cold roll steel. Good luck on this.
