66 Barracuda fender-mount turn indicator - screws?

Finally got a right side turn signal indicator housing to go with the left one I found at a swap meet. It even came with the lens and retainer plate!

Unfortunately, it doesn't have either the screw to hold the lens retainer plate into the housing or the screw to hold the complete assembly to the fender.

Can anyone tell me what size I'm looking for? Or if they are even standard screws, or in fact specific Mopar parts engineered solely for this?

Much obliged.
