I noticed that Ron at Bus Depot now has the replacement covers....that's
great!  I, too, was working on those as a replacement part but will scrap
that idea.  I do have, though, the replacement locking water caps if you
need that, too.  In addition, we can make the keys for your locking cap if
they are missing.  Thanks, Ron...that's a part we've needed for a long time!
  Good job.
