Per John Kuthe:
I'm gonna have to replace my crossbars pretty soon. Water got in, and
they are rusting at the ends.

Which begs a question: anybody know if SS bar tubes are
available?

On the fact of it, seems pretty simple: SS tubing cut to
length...

Maybe there's a diameter issue? (i.e. Yak's steel tubes plus the
coating they put on them might be some orphan size)
