Porsche bolt sizes

I'm having trouble identifying a particular bolts / screw size.
The parts manual says AM 6x15 screw...it is used for attaching the leading edge of the front door box.
I've searched the web for a reference to the size as the local fastening supplier does'nt know what it is or an alternative one to use.
Any help would be good

The PET shows this as a "half-round screw M6 x 15" for 70 - 73. Is this the correct year range? That should be easy enough to find.

Thanks for the info...thought it would be something like that.
The parts manual I have says AM6x15 foir some reason and I was a bit confused.

Thanks again
