    If I recall correctly, the core is behind the IP. I'd highly recommend getting a factory service manual to help you on your way. I don't think replacing the core is hard, but it will be time-consuming.

    I replaced the core on my 72 fleetwood. Not difficult just took some time. Had to disconnect the in and out hoses, then there were four screws on the engine side of the fire wall that hold the housing. You have to remove the glove box and some dashboard to get it out.
