I am looking for the air duct for the under dash air conditioning with the vent grilles and control switches for my LHD '97 Defender 90. I know some vendors sell an interior kit, but I already have the evaporator with plastic surround, blower fan, wiring loom with relays. I am able to jump the exposed connectors and it blows cold air, so I don't want to replace parts I have and are in good working order. If you look at the attached picture, I have part 48; what I need is part 94. Located in the DC metro area.
