There were some changes in location. Check out this counselor article, page 105packardinfo.com/xoops/html/downloads/SC/SC-VOL21NO22.pdf and see if it is applicable to your car.

Packard changed to a different valve with a different tube sometime after production started so it may not be applicable. On your square plenum cover or box, is there a small opening air can blow out anywhere. Later units thru 56 had a rectangular hole where the warm air would blow directly on the tube.
