I sure wish I had a 21.

Mine has "5.7" molded into the top of the hulls. If the hulls of yours are wrecked, there's not much chance the tramps or crossmembers can be used on any other boat.

I'm mostly intested in the tramp(s), and other parts of the rigging and fittings that didn't go to your new boat. Large things like the crossbeams aren't that important right now.

Even if I don't need them right now I probably will later, as the grandkids, college, school, and a dozen other things take priority over my sailing hobby, so the Gcat will be my boat for a long long time.
