C9ZZ-18A651-B Complete heater and power ventilation system control assembly includes bezel or face plate, knobs, bracket control mounting plate, electrical and vacuum switches. Functional, driver quality, heater control assembly. The power ventilation system was a pretty rare option for 1969-70. It included a center dash register as found on air conditioned cars and directed cool air through the center of the dash. Dearborn cars would have a code "VS" on their body buck tags, and Metuchen Mustangs would have the code "PV" on the buck tag.
*RESTORATION TIP* If you like to restore your own parts, you can purchase plastic polish for the lenses that will take out the haze with a bit of elbow grease. A silver paint pen (purchased from most artist supply stores) works great for the lever borders. Then you could score a set of our reproduction knobs, and you will have one mint unit to make that portion of your dash look killer!
