Hello,

The heater core was bad as it was out of a 1963 122 and it had never been serviced before. A custom core had to be made as you can not get a new replacement core right off the shelf anymore.

My radiator shop has access to a manufacturer who can build custom radiator and heater cores as well as custome made A/C evaporators.

In fact, when I went to pick up the heater core, I brought the empty heater box with me to consult with their techs to see if a smaller heater core could be built along with a custom A/C evaporator to create a sandwich of heater core and evaporator a la Volvo 240 design so that a bolt on under dash evaporator and fan assembly would not have to bused to get A/C in a 122. The techs agreed they could build both units. The next problem is to figure out to close off the fresh air intake with a moveable flap and route cabin air to the intake side of the stock heater fan so the cooled air could be recirculated.
