With the carbs and intake off, you can see the return port for the air conditioner oil line. A fitting is welded onto the engine oil fill tube. The return line was missing on this car. Since the AC system on this car is missing other important pieces I didn't replace the missing line.

I had trouble keeping wires on the engine manifold vacuum switch; the terminals were damaged. I found a new switch on line quick and easy and installed. I also installed the coil extension and the coil.

I looked for a self bleeding 160 thermostat and didn't have one so I installed self bleeding 180. On these 331 354 392 engines with the coolant cross over pipe, it is very easy to get an air lock below the thermostat. A self bleeding thermostat is essential.

There is a flexible gasket needed between the heater and blower box. Gary Goers used to have them but Quirey did not continue so you have to make your own. I use a piece of neoprene (rubber) 1/16" x 2.25 to 2.375" wide x 20.25" long. Use RTV to secure the neoprene and two sets of three 11" long zip ties as shown to hold rubber while RTV sets.
