What screws are used on 68 Barracuda Headlight and Grille surround trims?

Hello FABO.

Does anyone know what screws were used on a 1968 Barracuda headlight trim and front grille trim? (There is one through each headlight trim and one through each of the grille trim for a total of four). The trim pieces are the ones that have the black painted line running through them.

I have searched but have had no luck finding these fasteners or any info on the topic. My car has them missing - except one, that may or may not be correct. It looks like a stainless Philips truss head sheet metal screw in maybe a #10 x 1/2" long - but the back side of the head has a radial pattern that looks like it is designed to grab and prevent the screw from loosening. That fastener is installed holding one of the headlight trims on but is not long enough to use at the front grille location so I think there are different lengths needed for the headlight trim and grille trim.

Thanks for any help!
Here you go..

Cheers!
