Dash mounting bolt

I have a lot of hardware for these cars. The problem is shipping. I shipped one dash screw in and envelope and it came back. Went back to the PO and they wanted over $5 to ship it. The screw was free but not worth the shipping. Still sitting here on my desk.
Sad but true, I would gladly pay $5 for that one screw, spent a lot of time looking for one and a new reproduction set is $14 plus $5 shipping, and I don’t need them to be new… or shiny lol. I can’t substitute anything else cause can’t find anything else to use that fits the location due to thread style, head style, and windshield clearance. I know it would be ok without one screw but once the windshield is installed no going back… and I am already right there…
