I appreciate the kind words and I feel your pain. Parts shortages and lead times have put me in a bad bind recently.

Just to chime in on the freeze plugs. Nothing wrong with steel plugs if you coat them inside and out, otherwise they will rust.

Also, they make freeze plug drivers. The ones you show have been driven in with a hammer and socket, which leaves the ring in the middle as you see. Also, it kills me when they're not all aligned the same. The devil's in the details....
