Very Nice, I have been to that Drive-in several times in the 1990's to see movies ! Last i heard the city bought it. It was two screens when i went. Thanks for sharing.
About what size drill bit did you use ?
"I figured it out and got it done. Drill bit goes in the switch, bolt it on, with transmission in reverse. Slide switch to bump against the tab, tighten switch mounting bolts and check."
