Folks I have a problem with the AC ducting on my 91 Vanagon: it is sagging at the middle segment.  I had to take the whole assembly down some time ago to do some AC repair work in the evaporator.  When I took it down a lot of the plastic simply disintegrated so I had to fashion a bracket or 2 out of metal to hold the assembly in place as a way to substitute for the broken plastic.  I see that I will need to disassemble the ducting again to see how I can fix it firmly in place.  The question I have is: is there anybody out there that has new ducting or a viable substitute?? Any suggestions??
