1941 Pickup door hinge "backing plates"
 

My body man gave me a real scare earlier this week when he told me I needed all new door hinges for my 41 pickup cab! Fortunately, that is not the case. He later called to tell me that we need a square steel piece with 3 holes that goes inside of the door posts. He called them "backing plates." He sated that the piece is needed to align the doors. Does anyone know what these are called, and where I can get them? I'm a newbie at this. Any help is appreciated.

Make them from flat stock.

Just curious...were these plates standard back in the day? Or is it a needed repair to fix a problem due to age?

Re: 1941 Pickup door hinge "backing plates"
 

I'm not sure. The doors were removed for body work and the body man said that the plates were destroyed with rust and that we need new ones.

jmelcock OK then it sounds like they were original equipment. Thanks

My door hings appear to be riveted in place with 3 rivets. I think the "backing plates" back up the rivets. The rivets seem to have an extra wide head also. Been awhile since I was in that area of my PU.

Not sure about this but don't the hinge screws fasten through threaded holes in the backer plate? That would allow some adjustability for alignment.

They should be riveted to the door but bolted to the door frame.

Yup, riveted to the door, no adjustments possible without drilling out the rivets, shiming or hole elongating to adjust, and re rivet or shallow head coach bolts. They are screwed to the truck.
Not sure what your body man is on about, or planing to do here. Making they doors fit nice all the way round is a complete nightmare if you keep with rivets. They didn't fit perfect when new on these old trucks, they were work horses. Gotta keep that in mind.

OP stated "door posts". I believe that would be the cab not the door itself.

Flat plate. Drill, tap. It is a simple job for anyone with the most basic engineering tools.

As the bodyman describes is how all the 48 - 52 trucks are. The steel plate is captive in a sheet metal box inside the pillar that allows adjustment. I believe they are repro'd for 48-52, may be the same? Not hard to make tho, other than I believe they are 5/16-28 or something strange like that.

Got it,
I thunk he was referring to the front of the door, not the "A post" or "A pillar" as there known over here.
So as my buddy Mart said, flat plate, drill, tap, job done.
