I visited KCMongo's shop today and gathered some direct source pictures from earlier and later cabs/doors to help with showing the differences (yes there are some as Joe said) between the 1951 and earlier and 1952-55.1 strike plate mounting recess on the cab door openings, as well as differences in the latch mechanism and strike plates.
I need to sort out and title the pictures before posting, but will work on trying to get them up for all to see later tonight or tomorrow morning. More to come...
PS - Joe I have good news to share from Steve on sourcing your needed items. I'll contact you separately to give you the details I have.
