Needless to say, they have not been replaced, and yes, those screws are very difficult to remove. I often wondered if Allen screws would not be a better idea ? However, still have to get the old ones out !
Larry, do you have any impact driver bits or similar. If not, you could always make one.
Slide a ring spanner over the bit, engage it in the screw head, and tighten up the vice jaws to hold it in place; firmly but don't swing on the handle.
The opposing jaw will (hopefully) keep the bit engaged, to save it rounding the screw slot.
Apply pressure, or a mallet to the spanner, remembering of course which direction the bit is facing.
