Does any one know how to disasemble the heater box on a 68 to change the seals and paint the inside. I have taking the core out but don't see how to get the doors out. Does the box have to taking apart by cutting the spot welds to get to the doors?
You do not have to remove the main flapper door to replace the seal. I just removed the heater box and core to gain access to the door. In the seal kit, the main door seal will most likely have to be cut to the size of the door and glued down.Dave can the main door be removed to change the seal or do you just try to do it thru the opening under the heater core?
