Sometimes you need to clean things up & catch it in the act to find the source or sources. Very nice car! I too like the color. My first '66 was a martinique bronze LeMans with a black vinyl top. The color looks great in a subtle sort of way.

That's right. Lots of places up there it could be coming from. Clean it up and let it dry thoroughly and then start it up and let it come up to temp. Watch for it.
Another way, if you have a Stant pressure tester, is to use that. It's basically a small hand pump that screws onto the radiator cap fitting. You latch it on and pump it up to ~30lbs or so. Any leaks will show up. You can get one for 50 bucks or so on ebay or maybe borrow one from the local Auto Zone for free. They have lots of tools to lend out.
