Cooling Line help??

[Zippy]

'73, 340, 727 with Slap stick. Guess I should have taken pics. My two cooling lines running to the radiator come off the passenger side of the trans. I still have a fitting on the driver side just ahead and above the shifting and kick down levers. is this possibly for hard piping a vacuum line? Obviously I can't rely on memory any more. Thanks!!

both cooling lines come from the drivers side of the trans 1 in front of the shift levers one in the rear, Chrysler doesn't use vacuum to the trans
