Rear differential fill plug.

Rear differential fill plug.
I have a 1984 Ford F-150 4x4 and I am having trouble removing the rear differential fill plug. The fill plug is really rusty and there is almost nothing left of the square hole in the center I tried turning it out and the 3/8 drive extention wants to slip in the hole. What would be the best way to try to remove the plug?

Mine also has a bit more capacity too from what I recall. Nothing huge but it's around 1/2 quart I think...

I'm thinking about putting a bolt in the hole of the plug and welding it to the plug. Then trying to turn the plug out with the bolt. The heat from welding it should also help break the plug loose. I know I have to watch how hot I get the differential housing because of the seals and the fluid in it, but I think this will work. What do you think?
