I have 4 different kinds of screws holding in my dash. I figured it about time to address it. What kind of screws can I use?

your goin to need 2 different sizes,, one for the sides and another type for the top screws,, the top screws look alot like a trim screw with the ring washer,, needs to be pretty good size ring because of the top holes in the 65 dash bezel
