If the holes are not too big, the new thread might go bad in near future, because galvanic corrosion will resatrt with new screws.
If this is the case, you can rivet with those big aluminum rivets, and corrosion stops.
A friend once had that problem, and had to remove the mast, and insert a backing plate inside, then riveted it. He used alum rivets to decrease the galvanic corrosion. He also sparyed anti corrosion zinc oxide (from airplanes).
The mast was a selden, and the inside plate was easily made locally.
Hope It helps
