1970s windshield side chrome molding attachment screw

[Rockne Smith]

I'm missing a lower attachment screw on 77 Eldo windshield side chrome molding at bottom on A-pillar.  All large GM cars during that era used these self drilling screws on that molding.  Pic attached. I don't really need the self drilling feature, but would like to reserve the correct hex/fillips head.  Any ideas on a source.  Thanks.

Take the screw to Home Depot and match it up.
I replaced all the trim screws on the cowl when I restored that area,
SKU # 295 543 was the perfect replacement for my 1970.
