66 Barracuda fender-mount turn indicator - screws?

I have an extra original screw for the lens to metal plate/bezel attachment. PM me your address and I'll put one in the mail to ya' for free. Unsure of the correct size screw for the top screw...bezel base to fender connection.
Remember, make sure all connections & screws are secured snuggly before testing them. The base screw that secures it to the fender is tightened. It acts as a ground. The signal won't work otherwise.
