I don't believe you can mount '51 door handles on a '52 or newer door, flattop.
I replaced my wrecked '51 cab and left door with a '53 cab and left door. I had obtained some '53 handles but could find no way to make them work on the right '51 door. So, the left door has a '53 handle and the right door has a '51 handle.
I'm still working on the '51 striker plate on the '53 cab. It currently is functional, but I want it to be better.
I did some extensive measuring, drawing, and documentation on both doors in my journals, flattop.
I'll scan them and put them in my photobucket within the next few days and see if that helps you.
