Hi burrpenick,
Sorry, no parts to lead you to up in MA, although just a few weeks ago there was a Go-Wing here for $75 on craigslist.org.
On that note, just becareful if you have a Go-Wing sent to you. When mine was shipped to me when I got it on Ebay from a private seller, it was not packaged very well and got cracked. He said he was going to pack it well but due to the length of it it's easy to crack. (He just used a lot of cardboard.) It was an original '71 ABS wing, not fiberglass, so maybe the fiberglass ones are a little tougher. Fixable but none the less you're not paying for a cracked one. Just my
