The steel pipe that screws into the side of the carb slips into a small pipe in the exhaust manifold, at the back of the manifold near the transmission dip stick. See photo below.
The rubber hose connects to a piece of pipe that inserts into the UNDERSIDE of the manifold, directly beneath spark plug #5. This piece of pipe has a small bracket welded to it that is bolted under the head of the rear valve cover hold down bolt (along with the little metal bracket for the spark plug wire holder). The rubber hose is fairly short because the pipe runs up to just behind the carb. You can see it in my original picture behind the rubber PCV hose. I tried to annotate it in the photo below.
