(above) In the top picture, I put a gage temp probe near the grate and cut 3 holes in the lid and put a Weber damper over it.
(below) Here's the other pics of the mods...
I used Black high temp gasket maker instead of the orange or red (I plan to re-paint the whole cooker this spring).
The Charcoal pan sits on 3 screws where the legs used to be attached.
There is a rubber donut for the probe wires to go thru and you can see on the grill itself I put a little clip with hole to hold the temp probe for the Pitmaster probe.
I had to buy 4 U Bolts to get enough brackets to use on the 2 handles of the grill.
The water pan is not shown, but it has foil, then 3/4 sand, then foil for disposing drippings.
Also, there's no closeup of the wooden handles, but I screwed ends on them to keep the dowel type handles from working out.
