On a 1968 4/4

Sorry for bad technical English...

Driver door have free play.
Part of the free play come from the hinge pin (ok not a problem)

But I tighten the screw on door pillar and discovered that 3 of the 6 can't be tighen: I think there is a metal insert in wood that turn with the screw :-/ (They are metal screw not wood ones)

Wood pillar looks OK I think I just need bigger inserts (or glue actual ones?)

Any comment, pic or links warmly welcome to understand how this area is made and what solution could be.

First on the list of my winter jobs !

Thanks !!
