Part # request: screws under headliner

[Koizumi]

I can't figure out what the part number is for the screws that are under the headliner at the rear zipper that hold up the plastic panels under the foam. I was tracing down a rattling noise for months, only to find that these foam covered panels under the headliner were missing some screws.

Can anybody point me in the right direction?

Cheers
