Re: Mast mounting plate damage, repair or replace?
Looks like a POS casting. Take if off, now. No more sailing till it is fixed or replaced.
If there are any small foundries (art casting?) in your area, ask them about casting a replacement, maybe something better like bronze.
No foundries? The you go to a machine shop and ask them about CNC machines and if they can make a copy out of billet stock for you. A good shop with good people would have no problem with that.
Having the crack stopped, welded, and reinforced? Tempting, but heavy welds in aluminum that carries a load...easily screwed up, so make sure you're not dealing with a Bubba if you go that route.
If you can find a user group or run down the secondhand and consignment yards, you may be able to pick up another old one. Could take several days of phone and email work, but might be worthwhile.
When you put the new foot and screws into place? Use plenty of neverseize or galvanic paste, because dissimilar metals will try to either seize up, or rot each other out. FWIW.
