Well, after declaring my Underground Firebird on a forum post last week as being "indestructible" two days later, I managed to lose one of the large rear fins, along with the hold-down bolts.

Anyone have any suggestions for where a replacement might be found?

Emailled Underground, but it seems they have relocated to Maui and the person who replied to my email seemed to have no idea what I was talking about.

Any suggestions greatly appreciated.
