Correct Interior Screws ??? Help

I am starting to replace some interior pieces and want to make sure I am using the correct screws and fasteners. What would be the best way to find out what the correct one is?

Thanks

Hello

If the car wasn´t restored befor then the original screws are still on ther place. So you have a sample.

Also the Porsche Spare Part Book covers each screw and washer including there DIN number.

If you get stranded you just order them new. Some screws are NML and replaced with newer versions.This is the easyest way if authentency/originality isn´t a major issue.
