1959 Electra Door Trim Screws - Please help

[JonPHG]

I need a little help please.

 

During a re-trim I have lost all the door handle retaining screws.

Front and rear doors.

I have no idea what diameter they are or how long they are.

What is the form of the screw thread and what does the head look like?

 

I'm not really sure where they fit either.....I think I can feel the screw holes through the new vinyl.

Do they have a cup washer under them?

 

If anyone knows or can take them out, measure them and maybe post some pictures of the screws and where they fit it would be most helpful.

 

Thanks in advance.
