Dan - The qualified dimension is between the broached pad face and the threaded hole for the water pump attachment. If that dimension is too small, the pad could have been decked.

John, I would say, take the car on a trip, and spend a few key days in the area. That looks like a small town. Take it to the best turn out car show (I see there is one there, with a quick search). That is a unique stand out car, somebody will know it.

Also call the local town NAPA and other car shops, somebody may know it that way too. Maybe call the paint shops in town, if its been repainted once (which I believe it was).

I have had good luck doing things like above. Small town = good news.
