Interior Screw Guide

Hey all,

I was taking my interior apart to restore, and noticed a lot of my screws throughout the interior weren't matched correctly. Areas like the a-pillars had different style screws, the rear window plastic trim as well.

Is there a couple of generic screws that will work with all the interior pieces, or is there a guide somewhere? I'd like to go source all brand new ones if possible. I feel like taking the ones I currently have wouldn't help since they're all a big different and mix matched

And I know certain areas of the interior have longer or shorter screws depending on the pieces, so I have that challenge as well.

Any help is greatly appreciated.

I started putting a list together a while back but nobody was interested so I gave up on it. Most are a #6 or #8 phillips pan head or oval head screws of various lengths.
