I ended up getting a call back from bbq guru today and she confirmed what I already found out from Jerseydrew. The outside diameter of the nose is 1.209" and the inside diameter of the adapter is 1.219" and needs to be at least 0.60" deep.
I have some pics of how I set mine up that I will get uploaded tonight and post here.
I managed to get a couple pics of my intakes up on photo bucket today. You can see the 2" female fitting on the left that will have a sliding damper or a round cover that will be on a threaded rod and spin out. The one on the right is for the guru. I made it out of a piece of 1" pipe with the inside turned to 1.219". I will also be machining a kill plug for it too.
