Yes, the heater box was redone. I bought it at Carlisle from "The Heater Box Guy". It's not perfect...it looks like there was a small chip in the front cover so he filed that edge down. The heater box cover has absolutely been the hardest part to find for this car. I don't want to use a plastic one so I've been searching for a good original for 2 years now.
The shop is Labrecque Autocraft in East Windsor, CT. He's about 10 minutes from where I work so I can stop in anytime. He does specialize in Mopars but he will do anything. He's had a lot of interesting cars come through. He just got an AAR Cuda dropped off that a guy had been storing for 30 years. Its rough!
