New Braunfels Smoker

Howdy all. I have the classic New Braunfels Black Diamond smoker that I am almost 10 years. I work a lot. However, when the movers we moved from Georgia to Louisiana, they have lost the little cap that goes on the stack. Now I can not control the temperature of my grill with great precision and it is unusable as a smoker. Obviously, with the college football season for us, it's time to start smoking Briskets so I need this problem resolved. The only problem I have is that I can not find replacement caps EVERYWHERE. Does anyone know a place that sells these? Thank you in advance.

Charbroil bought New Braunfels Smoker Company. Here is a site where you can find the missing part:
