I know they are in MI, but can't be more specific.
PM Spydermike or BBQBubba. They ARE GLBBQSC and they've both always been very helpful to me with any questions I have. OR you could use the "contact us" email option on the website. They've also always promptly replied to that to me before.
Those guys ROCK!
