    New Heater Box for my 67, where do gaskets go?

    I guess when they sell you these things, they assume your old setup had everything there so you didn't need any instructions... NOT! Needless to say my old box was missing parts and gaskets, so I don't know where they go.
    From the first picture below:
    Does the larger round gasket go between the fan & the firewall (naturally on the inside)?
    Where does the smaller oval gasket go?
    Does one square gasket go between the heater core and the back part of the box?
    From the second picture below:
    Do I have the square metal plate inserted correctly and does the gasket go between that plate and the heater core?
    THANKS for any help.

    Looks like in the picture #18658 is the rectangular gasket that goes on both sides of the heater core. #18583 is the small oval gasket and it appears to go between the blower motor and the firewall. I cant find the round gasket.

    THANKS 67Catmando, very helpful. The previous owner really made a mess of things. He broke the main part of the heater box away from the blower housing part of the heater box, I imagine to replace the heater core because the hoses and clamps (not to mention the heater core) look new. Then tried to glue it back together. I was getting very little heat due to the blower sucking in air from around the back of the box and not through the heater core. What a moron! I also got one of the new plastic plenums. The old cardboard plenum is rivited onto the heater box and probably would have gotten ruined trying to remove it. Anyway, not that I drive my cat when it's cold, but it's good to have it working in case. Looks like the little oval gasket #18583 goes between the motor part of the blower and a plate which sits between the motor and the "fan". The round gasket #18570 goes between that plate and the firewall. Once again... THANKS!

    Im having almost the exact same experience with my heater box. The bottom half is missing, together with the heater hoses being disconnected, the Air conditioning disconnected as well. Luckily its not so cold here in southern california, but one day ill have to dig into and figure out much like you do, where and how pieces go together.
    Good luck, and let us know of your progress/success !

    I just got done installing the heater box and I must say it was not hard at all. Basically everything is assembled outside of the car. Put the heater core in the box, attach the blower and hoses to the heater core, and pull everything through the firewall. I don't have a/c so I imagine it's much harder. But if you only want heat it's easy. Any questions, don't be afraid to ask.
