How I repaired by Form 1+ with a second-hand part, some acetone, and a pack of Sugru

I just got a used Form-1+ which was sold as not working, and I can see a galvo is missing the mirror. I checked the links on some Form-1 page that discussed sources for spare parts, and the links are dead. I am looking for the Y-axis galvo if anyone wants to sell one. Thank you.
