Wood Speaker Cover - Need Description of Screws

[JPMOSE]

I have a small pile of screws and can't figure out which two are for the speaker cover!   Could someone describe approximately what length and finish the subject screws are?   

I'm usually so good about marking and separating items but blew it this time.  Thanks in advance!

They're quite unusual screws; around 20mm long self tappers, chrome plated and thin (around 2mm).
If you gt stuck I can provide you with MB part number.

Thanks....then that means I found one of the two!   I have the part number but it is NLA (at least is was for my 280SE 3.5...I'll check the EPC and see if they're the same part number).

A picture's worth a thousand words!  Thanks to both of you!
