(1) Check the "Parts for Sale (Private Classifieds)" section of this forum and see if anyone is selling theirs. I sold mine thru here.
(2) Check Craigslist. I have seen some racks posted there.
(3) Another option would be the SeaSucker system. I sold my Boofsquire rack to buy a SeaSucker Talon for my mountain bike. The main reason I sold my Boofsquire rack is I need a rack compatible with any vehicle. I did check SeaSucker's website and they do sell a
surfboard rack. It is about the same price as the Boofsquire rack and will be compatible with any vehicle (a plus in case you need this option).
