AC Line Update: I've been doing a little more work on the routing of my AC and heater lines. I drilled holes in the bottom of the passenger side fresh air vent in order to mount my AC/Heater bulkhead. I drilled the first hole and then realized that layout wouldn't work. I ended up with an extra hole, but that will be mostly covered by the bulkhead. I'm not worried about it.
I mounted the bulkhead from inside the fresh air vent. I know it looks weird with the good side hidden in the vent, but this will allow me to remove each of the connectors and make the connections with the hoses outside of the vent. Otherwise, I would not be able to get wrenches inside of the vent to tighten the connections. I originally wanted to put grommets in the bottom of the vent, but it was impossible to bend the AC and heater hoses.
Here is the bottom of the fresh air vent, where I will tighten each of the bulkhead connectors.
Here is how the AC and heater hose fittings will come out of the bottom of the fresh air vent.
I slowly keep banging away at it. Peace Out!
