Be glad it is not the one behind the engine mount
Right!!
It is definitely the freeze plug. I was Planning to try and get a metal plug in to replace it instead of the expandable rubber ones mainly because I like doing jobs right the first time. Upon closer inspection of the other freeze plugs it looks like the previous owner had a freeze plug issue as well and used the rubber ones. I have owned the car for 3.5yr and it still isn't leaking.
Long term plans are to pull the motor "one day" to freshen it up. Thoughts on using the rubber one as a patch until I can pull the motor to do them all the correct way. We are about to get into the fall here in texas which is some of the best cruising weather. Already in 2015 rebuilt the whole front end, upgraded to disc brakes, all new brake lines, booster, and MC, rebuilt the carb.... I love a project but I would like to put some miles on the old girl.

As I said, I would use an expandable type freeze plug.
One of these:
No rubber, they are made of copper. You should be able to get one about anywhere... I think Dorman makes them.
AAP has them in the store behind the parts counter.

Now is a great time to do a real good flush of the cooling system and install fresh antifreeze.

Evaporust if its nasty
Now I am paranoid about the other freeze plugs after seeing this. The big hole was my screw driver the pin hole was the elements of time. I checked the other plugs and none were leaking ...today. May change after filing her back up with antifreeze.

Didn't know they made such a thing, I thought you meant the rubber one. I learned my new fact for the day.As I said, I would use an expandable type freeze plug.

That should baffle the zit-face behind the counter.

They salt the roads in Texas?
No salt here except on your corona. AAP didn't have the brass expandable. I got a traditional steel replacement but nobody has a freeze plug tool in town to rent. Auto zone is bringing one in tomorrow for me to rent. Never fails

A socket with the exact diameter of the lip will work.
