If I'm reading this and looking at it right, the holes in the bowl are right at the leg sockets.
Just wondering if they would interfere with the ash sweepers?
In the following link, it shows the schematic drawing, with the ash sweepers I want to get. Part # 90992.I click on it, and it shows a pic with the H used in the gold ash sweepers. Is that part # I listed a good one? Are these the ones I should order?http://www.ereplacementparts.com/weber-1241004-2010-one-touch-kettle-grill-parts-c-193079_193086_193480.html
The ring doesn't attach via the ash sweepers anymore, the the regular ol' 18" ash sweeps (either new or old) will work for your silver or gold ash catcher. From the looks of things on the Weber website, the H-style is only 22.5"
