However, you can get it to work on any A-D cab, but using the 1951 and earlier door latch/striker(catch) parts.
Thanks for the reply, Tim.
I'm gonna go ahead and try the '51 setup on the right door. My main concern there is the fact that the area where the striker plate mounts is different on the '53 from the '51. The indentation on the post of the '53 cab is shorter in length than on the '51.
I've not attempted to deal with this situation empirically; only through measuring and whatnot.
I'll keep you apprised of the status.
Thanks again.
