This is the proper heater plenum for CJ5, CJ6, Pick Up Truck, Station Wagon and Sedan Delivery models. This has the flap to divert the heat to the floor or the defrosters. It has 2 connections for the defroster hoses. The defroster duct is made of plastic instead of cardboard that rots away. This is the style plenum that is used with the cable setup not the vacuum canisters. Made in the USA.
Note: On CJ5 and CJ6 models the one hole is the one hole is blocked off and a collar is needed to step the hole to the bigger diameter hose. (This is how it was done from the factory).
1 Required per Jeep.
