freeze plug leaking

I have a 318 in a 74 Duster. As I am trying to get all the leaks, rattles, and thumps addressed since my son bought the car the recent challenge is two freeze plugs leaking. They are leaking from the freeze plug itself via little pin holes... not from the edge seam where the freeze plug seals against the block.

My current thinking is to drain the block of anti-freeze and clean and dry the freeze plug... then JD Weld it. I really do not want to pull the engine out right now as I have so many other projects going on.
