Winters are cold here so one of my first fixes will be the heater. The levers were broken on the original unit so I ordered a used assembly from eBay....turned out to be worse than mine so I ordered levers and knobs for the one that was already in the truck. Managed to get all of the cables and heater doors working and the mechanical will be good to go. Here are some pics of the two heater controls....notice how the lever that operates the heater switch is different.....also the cable attatchment points are not the same distance from the pivot rod. The OEM 1966 control is on the right and the eBay one on the left.
