so i just contacted weber inquiring about stainless steel sweeps.
people have talked about parts 90720, and 90993, which according to weber are BOTH made of stainless steel, and from what I can tell they BOTH use the H drive vs the really old school hex nut.
however, the CS rep at Weber gave me the impression that the two are not interchangable.
on top of that, they have both in stock as well, but 90720 is $13 more expensive than 90993
anybody have any insight that would be a little clearer than mud?
