34 dash screws, what were they?

[cas3]

the two in the lower outside corners on the face of the dash. the hole seems to be 1/4", there is a recess there for a pan head screw? or oval head counter sunk? nickle or stainless i presume? it seems none of the vendors carry them, and hardware store stainless stuff is phillips head (yuk) are they the same as some other part that is available, like dovetail screws? thanks, skip
