Hi Dave,

It could be welded. Or you could drill & tap & put a screw in the hole. 
For that matter, clean the spot thoroughly with acetone or lacquer 
thinner & smear a dab of "JB Weld" on it. If this doesn't work then try 
something else. There is a possibility that the pin hole opens into a 
much larger cavity underneath. If so, the JB on top would be the better 
bet since welding might lead to a much larger hole. Take your choice.
