1965 anti-theft possibilities?

[sfalco1957]

Hi, just got a 1965, 10 year-old restoration. Since you can steal this car with simple hand-tools, and there is no hood lock, are there any anti-theft options? Perhaps a keyed switch that can be mounted under-hood, something to make things harder? Not that I plan to leave this in a high-crime area, but if there is something simple I can use it would be helpful.
