I am clearing my father's estate. Most of his fixations were on cars newer than those the Jalopy Journal caters to. I am finding stray parts with older applications, though. This is something I haven't found a lot of information about. Hoping you have some insight to share. The box is in terrible shape. If there ever was a part number, the flap which carried it is gone.
Looks like this device is for changing the transmission "switch pitch " mechanical linkage to vacuum control from engine.
