For sale is a nice 1969 1970 original Mustang Cougar heater box front or cover.(non AC) My original complete box was damaged at the back by someone replacing the heater core years ago, so I had to find another box. The box I purchased is either later or earlier, the cover does not fit well with the box I purchased or I would keep as a spare. This cover came off a heater box that has the full stud(car was built in November, 1968) for the outlet vent to attach, the box I purchased has the short nipple instead(so a variation in the product cycle), see last two pictures of the difference in stud and nipple for detaching defusing vent.
