A family Parker

I need some more advice. The trigger guard strap is frozen in place--presumably by rust.
Obviously, I will need to free it so I can pivot it out of the way when remounting this assembly on the stock. I've cleaned the painted finish off the base of the strap since this photo was made, and I have had Kroil soaking around the base of the strap screw for a day or so. Now, for a display of my ignorance: There is another threaded hole in precise alignment with the strap pivot hole. It's on top of the trigger block in this view. It appears only to go through to the trigger plate, but it's very difficult to tell for sure. If this were a single threaded hole, running all the way through the trigger plate, I could use the Kroil in the shaft, and get more direct flow to the threads below. Could I get that lucky? I doubt it, but I'm sure some of you have dealt with this ahead of me. Thanks for any advice you can give.
