I'm interested in this also.
Of course now I need to go give mine a look. I haven't been getting too close to mine because I don't have time/funds right now to tear it apart and i know of I get too close I'll lay a wrench to it.

I found this as you probably have also it has contact information someone there must have some idea.

And I got this pic legally from flicker. Something about having licensing blah blah.

Anyway if someone on here still makes waterslides I would be more than happy to give them the file.
