Looking forward to how your brisket turns out.
I think I saw that somewhere. There is a bolt on the back of the chamber by the chimney. Is it bolted in? If so I may remove it and fit something between the chimney and the opening. I used high temperature silicone on my WSM for a better seal and that might work well here.

I'm happy with the results so far but I have much to learn. I opened the cooker to put a probe (ET-73) in the brisket and it is at 181° and inching up. It is coloring up nicely. I'm using my ET-732 to get the temperature on either end of the grate and the end toward the fire box is running about 40° hotter. Right now it's 288° vs. 250°. When I added the ET-73 I put the cooker probe next to the brisket in about the middle. It's running about where the hot end is or even a few degrees hotter. It's probably close to the 2" gap between my "tuning plates."
I'm surprised by how often I need to add wood. It seems like there is a relatively small bed of coals and fresh wood joins it rather rapidly, particularly the box elder. Both are pretty dry. As a result I need to add a couple sticks about every 20 minutes. I'm wondering if larger pieces of wood would provide a longer burn w/out spiking the temperature. It looks like I'll consume all of the wood I prepared before the brisket is finished so I'll try splitting some more pieces a little larger. <need to run out and tend the fire> I seem to be getting relatively clean smoke. I get a little white when adding wood and most of the time it is barely visible.
Woops! Preheating some sticks in the firebox has it's risks. It can catch fire and spike the temperature.
Edit: I do have temps at three points across the grate so I can see what the baffles are doing. In the picture I showed one up against the other but I thought about it some more and opened about a 2" gap to allow some heat to come up after the angled baffle.
