Door won't stay open

[JerryinTx]

The Driver side front door on my 48 Plymouth will not stay open.  All the other doors on the car do not have this problem.  Is there an adjustment that will correct this problem?

look for the clip to be broken out of the door second layer metal...

Had the same problem with our Dodge up to a couple years ago.  There is a bar of metal towards the bottom of the door that limits how far the door can be opened.  It is attached to the front door post, but slides in / out of a slot in the door.  On the end of the inside of the free end is a rubber bumper that cushions the door when fully opened.  Just before that bushing is an engineered thick spot / dimple in the metal strip, not machined in, most likely pressed.  It is what works with the clip Plymouthy notes to hold the door open, that clip was still in my door.  That dimple gets massaged flatter over time to the point it won't hold the door open anymore, especially the driver's door.  That bumper is removable, I removed it, which allows the door to open "too far" and the metal bar to come out.  Some persuasion with handheld impact tools restored the shape of that hold-open dimple, and some "reverse of removal", and now the driver's door is held open.  I've a friend with a '46 D24 that had the same problem, he chose to remove the rivet that holds the bar onto the door post and removed that bar by pulling it back into the door.  You have to be careful what you reattach the bar to the door post with, as it has to fit into a slot on the door when closed.  You do have to remove the door panel for either procedure.
