Help finding a couple parts

[minskbeetle]

Working on my first Westy - 82. Looking to find a few specific parts, have no idea where to find or even look after scrolling through countless pages on vendor websites. Maybe someone can point to me a quicker/better source:
- Piece of ducting (plastic I think) that runs from the electric fan mounted in front of the tranny/motor to the cabin fresh air (heat) inlet tube before it reaches the cabin.
- Partial wiring harness just for the motor. Pulled motor for a rebuild, a lot of the wires are pretty baked from years to work in a hot environment, would prefer to replace them while the engine is going back together, but not going to do a whole harness on the bus right now.

Thanks in advance for any help!
