Seems like deja vu all over again. I made the same mistake. I bought stainess door window trim for my '54 3104 thinking that all AD trucks used the same trim. The trim was from a non-vent window truck. Still have all four interior and exterior stainless pieces.
The interor window trim on 1947-1950 non-vent window doors was thinner than 1951-1955(first) vent-window doors. The method of attaching was also different. Don't know if you could modify non-vent trim to fit a vent-window truck. I believe that it was discussed on Stovebolt a while back.

The 1951 model may have been the only year that stainless interior door window trim was offered on vent-window trucks. I don't think that any supplier makes reproduction stainless interior door window trim for vent-window trucks.
Chrome plating may be an option for your interior trim. A previous owner chrome plated the interior trim on my truck, shown on the right in the pic above. It had pealed, pitted, and rusted by the time that I bought the truck. I cleaned it up, epoxy primed, and painted it interior color
Glad that I didn't install my interior or exterior stainless door trim. I learned later that stainless wasn't offered on my standard 3-window truck.
The exterior trim will fit all AD trucks.
