Looking at replacing or updating the climate control valve assembly on my 87 w900b and wondering who might have one as mine leaks air like pouring piss out of a boot. Heard from someone that cat was selling a retrofit kit to install the newer style but having no luck finding it. Found one that looked like junk on vanderhaags so that would be no better than what I have now.
