For the new stuff, I get it. These grills are made in China, and my guess is they have a parts run for expected number of warranty items. Parts run out and it is not cost effective to make more.
I'll be candid, I never expected that the E330 parts would not be available, so it's good to know that now. I've got a little rust and I'll attend to that before winter.
Maybe I'll take up TIG welding as a hobby when I retire.
For the older stuff, I guess I was hoping there would be an option, and if it was simply grind a 16th of the pan away then it seemed good. Well for a few minutes.
