My mirror screws into a small piece of metal which has broken off.
It looks like it has been broken off and welded back on before.
I want to use something like this to make a new mounting hole for the mirror, but I won't be able to put it on because this metal is in the way. Does the piece of metal that is there look like it can be hammered off? Or is it welded on too strongly?
Otherwise, how can I fix it? Do I have to have it welded on again?
