thanks everyone for the help... i will get the replacement part. i find it odd that there isn't a shield across the entire front of the cookbox... i suppose the extra searing burner tube is the reason. found it on amazon as well... https://www.amazon.com/exec/obidos/ASIN/B072LGR17Y/tvwb-20
i have a weber EP-330, and was recently cleaning it out. there is a 'plate' mounted inside the front edge of the cookbox, over the 3 left burner tubes (left, sear, and center). it is all rusted out, as you can see from the attached picture. there isn't an equivalent plate of the right most...
