Just wanted to let you know my experience with this.
I read through Dons thread about replacing the core and the mods he had to do to make it fit. I was ready to make the same modifications to my unit as he did. I had the heater core out with me when I went into the parts department at FOT to see about getting a new one. The only one they had was the same one Don got from them. While I was there, I stopped to talk to Alton in the FOT shop about something else and get his take on installing the heater core. He said to take the heater core to Durham radiator service in Lufkin, TX. Thats who they use. I also asked him how to repair the drip collection pan inside the box underneath the heater and A/C core(FYI, radiator coolant degrades the plastic parts inside the box to the point that they fall apart) . He said, dont bother repairing it take it down the street to the sheet metal shop and have them duplicate it in metal. when I pulled the box out, the rear plastic housing was also damaged from the coolant and would not seal against the fresh air intake so I had that made in metal as well. While in there, I replaced the speed control switch and the blower. I also put a coat of paint on it because radiator coolant also removes the galvanizing.
The repair for the radiator was about $85. Durham said that if he couldn't repair it he would re-core it but the repair did the trick.
Hope this helps.
