Finally, an answer to the much needed, delicate 1968 air conditioning side vents! Visually, these are very hard to tell apart from the originals we have listed on this site but functionally they are much better in that they are cast in one piece. The originals were very prone to breaking and often when you close the door on your 1968 Mustang, Cougar or Shelby the lower portion of the vent falls off. This kit is correct for the 1968 Mercury Cougar only and it includes all three knobs, right and left vent assemblies and center vent with cover plate. You will be installing your original fan switch and vacuum switch as well as the related linkage parts.
