[hypoxia]

Coach 1482 The bumping sound when the pocket doors opened and closed was annoying.  I read up on the solutions others posted but no joy.  My solution was to cut a 1" long piece of 1/2" ID vinyl hose which is 3/4" OD and stick it in the doorway near the top with double sided tape.  No more bump.

I did gain access to the rear bath air valve so here is a list of photos and files showing the part numbers.
