Late Vanagon Westfalia A/C into a 1974 Bay Window Bus

I just finished a five-part short video series documenting the installation of a late-model Vanagon Westfalia A/C system into Judy’s 1974 Bay Window Westfalia.
This Bus is running a Foreign Auto Supply Gen 5 engine conversion, which we installed as part of a larger light-restoration project. The A/C setup uses the Vanagon rear headbanger cabinet, evaporator, blowers, ducting, controls, relay/fuse block, wiring harness and refrigerant plumbing, adapted into the Bay Window interior.
The five videos walk through the system from initial component layout through fitting the headbanger cabinet, evaporator, wiring, drains, penetrations, plenum and final topside installation.
What remains is the final refrigerant hose work, condenser mounting and commissioning. Before finalizing the condenser location, I’m also checking with FAS to make sure the planned placement works appropriately with their Gen 5 cooling-system setup and warranty requirements.
For anyone interested in the whole project, there’s also a walkaround video from when the Bus first came into the shop, plus a quick final walkaround shot just before the customer picked up.
If there’s interest, I’m happy to keep documenting the final hose/condenser/commissioning side as we complete it.
