Does anyone have a source for replacement parts for factory AC? I managed to smash the duct that goes to the passenger air vent to day trying to drill out the bushing under the floor pan on that side. The main unit it the middle has broken around the place where both screws attach it to the dash above as well. I can at least run self tapping screws through some of the meat of the plastic next to those if need be but the passenger vent duct is obliterated.
