There may be a photo on site but I believe the six with PCV systems had a fitting the copper tube attached to that would fit the same hole the road draft tube normally used. Look at the right side rear of the block just above the bellhousing where a road draft tube would normally be attached and see if the tube ends there. For the eights that had an adaption, I believe the opening was in the center of the rear valve cover.

Finding an authentic Packard valve may take awhile but I am wondering if something else could be used. There was mention of a similar looking Jeep valve in that other thread that might be an option. Since passenger cars did not have PCV maybe removal and back to stock is an option too.
