What about the wire they use to suspend a grid for a dropped ceiling? Should be able to get it in HD or Lowes It's just a little thicker than hanger wire. (Or maybe the aluminum wire they use to tie chain link fence to the posts)? (What about bailing wire)?
The windshield should have a stamp on it some place saying who made it. The old ones on the v20 was a Taylor brand. They did not make the windshield any longer, but at last look they still had hardware for them.
