The manufacturer indicated my cab must be a 52 (or later) and their pictures of their latch kits show a flat striker plate for that vintage. I have asked them to clarify the bolt spacing and the bolt size.
If they are correct that means my truck titled as a '49, has the frame of a '50 or later (tube shocks), and a '52 or later cab (although the doors are pre-'52 as they do not have vent windows). I am not familiar with the differences between the model years other than the shocks and vent windows in the doors so it may be interesting to sort out what model years I actually have for the various big picture items.
