i have a diffused downstem in my 16" RooR yellow label.. well it got fused because water got between the glass on glass and it acted as glue. well today it chipped so i had to get it out of the bong. when i was getting it out it snapped in 2. so now i need to buy a new downstem the main question is. i need to know the sizes for it so i can go to a headshop and get a new one here are some pictures yes i know my RooR is fake so dont give me any bullshitt http://i574.photobucket.com/albums/ss187/zeroskater199000/roor.jpg http://i574.photobucket.com/albums/ss187/zeroskater199000/RooRSig.jpg
