Looking for Backrest Bladder for Gliderider or Stealthrider

I know it's probably a long shot, but I'm looking for a backrest bladder for a Wood River Stealthrider or Gliderider float tube (they're basically the same thing). These float tubes aren't made any more, and I'm hoping someone has a backrest bladder from one that had a failure of the main bladder, or something like that. If you have one that you'd part with, or know where I can find one, please let me know! [You must be registered and logged in to see this link.]

Thanks!

Looks like these guys carry the tubes...
might want to hit them up and see if they have just the bladders or point you in the right direction.
