1940 Ford Pick up Passenger Door Lock

When I purchased my truck there was no key to the passenger door lock. I picked up a vintique repop door lock assembly and possibly an NOS or older after market door lock with Yale keys. I would like to install the lock with the Yale keys. But there is the problem. The set screw that holds the lock in is missing and the set screw hole is about the size of a dime which means at some point the set screw hole has been jacked up and over sized. So my question is does anyone have any ideas of how to get the lock assembly to stay in the door? The access hole to where the set screw should be is too small to take a picture. I could use an adhesive in the lock cylinder hole but I'm apprehensive to install it like that. If anyone has installed these locks you know the set screw side is not accessible to modify at least from what I can see.
Any advice is appreciated.
Thanks

There should be a hole I think about 1/4 inch (originally) then the set screw. Is the first hole dime size or the actuall the set screw hole? I'm lucky both my 47 and wife's 41 were all there and set screws.
 
I didn't think Ford put P.S. locks in until '41. That's maybe why there isn't a set screw hole. Also in '41 the lock has a u-joint in the shaft that fits into the door latch to make the lock and latch line up. Same on a '40?
 
A threaded tube is attached to the door frame. A long screw is run down the tube to meet the flat portion of the lock assembly. The correct length would be when the end pushes against the lock and the other end is flush with the door jamb. The pressure against the lock keeps it in place.
 
Now maybe I can finally get the lock cylinder out of my panel's pass side door. I have the tube and I'm guessing the set screw is sort of deep in there. What am I looking at for a screw head? Slotted? Probably not allen, but??

You should have been able to take the old cylinder, once removed, to a good locksmith with some blank keys and have them re-key with the code on the cylinder.

How was the old one held in there without the set screw?

Someone must have drilled out the entire setscrew hole and post because at a dime size the whole thing would be gone :( So you cant tap it.

Not sure I'd glue it in there.

Maybe some sort of collar with a replacement setscrew piece (short round bar drilled and tapped, then welded to the collar) would work. But it would be difficult to adhere it to the door... you'd most likely have to remove the door regular to get it in there.

Best of luck.

That's good to know Bruce. I had no idea that they used allen wrench screws that far back.
