Dome Light and Interior Screws

[SDSkyliner]

I'm working on the trim screws in my 1957 Skyliner. The previous owner gave me the dome light for my car but it was not installed. I've tried a number of screws to install it but have not found the correct ones. What size/style should be used on a 1957 dome light?
Also, what size/type screws are typically used to put on the interior trim around windows inside the car? I'm thinking they are #8 or #10 screws. I'm having trouble with the moulding on the driver's side immediately behind the driver's door. I'm thinking the wrong screw is in it as I can't get it to tighten down nicely or the threaded screw hole I'm screwing the screw into is in poor condition. Some advice on what the right screw is or if its tapped out so to speak and what to do would be appreciated. Thank You.

I saw this on e-bay, might be something you can use.
