I got the dash and instrument cluster out and I was able to eventually pry the top portion of the heater box apart and wiggle out the heater core. How did other members get their heater core out? There seems to be a large black bar running across the lower portion of the heater box and attached to it are several wires and vacuum lines. I haven't ordered the new one yet, but my options are BEHR and NISSENS.
