Hello,
We finally took time and got the two plugs out that had broke off.
Just used drill bit to take them down smaller and a hacksaw blade to put some notches in them without going to far to damage threads.
Used a punch and chisel to break them a loose, then put ease out in one and it spun out and another drill bit in the other and it spun out also.
Have them rethreaded now for new plugs.
