When I worked at a gliderport in the 1970s, we treated most of the
2-33 forward fuselage structure above the level of the floor as non-
essential. All the real structural meat is in the triangulated truss
that supports the seats from below. Above that, the tubes smaller than
about 3/4" in diameter are mostly there just to support the fabric and
nose fairing. So I'm guessing that the damage you describe is pretty
much inconsequential, and that if you can find an A&P familiar with
the 2-33 structure the repairs will be pretty simple.
