1966 Valiant Turn Signal/Park Light Lens Screws

I just got a 1966 Valiant this week and it is missing the Turn Signal/Park Lenses in the front bumper. Classic Industries has the lenses and the gaskets, but does not list the screws to attach the lenses. I contacted them and they state they do not know the correct size screws to attach the lenses.

If possible can someone measure the screws that attach the lenses? I may be wrong, but I believe they have a shoulder of some length.

It seems to me that they should just do some research and offer the lenses, gaskets, and screws as a single part number kit, but what do I know.

Thanks in advance for your time and trouble.
