Where to find Gas Cap for 22v??

I lost my gas cap in the lake yasterday and need a new one badly. it came disconnected from the chain and i couldnt get in quick enough to get it without dropping my gas can in the lake too. It is about 30 ft deep where it is so i couldnt find it in myself to scuba down there..


I have a 2004 Tige 22v...

If anyone makes anodized ones or anything bling thatd be cool too. Thanks alot
