I just called horizon and told the guy what the deal was. He looked and said that he did have the wings in stock in a California warehouse. He's shipping me some out and also sending out a call tag so I can ship the other wing back to him. This is exactly what they did when I had this problem with my ultra stick.

The nylon bolt I got from lowe's 1/4x20 worked perfectly. tightened the wing down snug.
