heater duct parts source?
Previous owner(s) had torn up the underside of my car's dash pretty badly. Wiring is a bit of a mess, and some pieces are missing.
For example, some of the components of the hvac ducting off the plenum box are absent. I have found most of what I need, but so far have been unable to locate one piece in particular.
It would be a section of (I presume) plastic duct which goes from a square opening on top of the plenum, to a rectangular vent which is part of the heater controls. (This is an AC-equipped car).
Any suggestion on where such a piece may be located?
