Sorry to say that I also found out that one must order parts through the dealer. But I haven't checked for some time.
The only time that I was able to get parts direct from GS was at the Gulf Streamers Back Home Rally.
If you want to verify this, sent an email to:

Brian is the Parts Manager and he will be able to tell you if you can order direct from them or not. Let us know what he says.
