I had one block were a previous owner must have done the same thing, I
couldn't get two studs to turn. The one in the front was easy, I could see
that a hole had been drilled and tapped from the side of the block an I was
able to get the set screw out after much effort. The long stud was harder to
identify and I finally figured out that the guy had drilled through the stud
hole into the bottom end and tapped that hole to match a threaded hole he
created in the long stud. After all that I junked the block because I have
spares, but if this is a restoration this technique would probably save the
block. Truth be told, if I just knew about the locked down studs before I
manhandled them trying to get them out I probably could have easy-outed the
set screws, or just left them alone.
