Weber support may replace the cook box. They did for my summit 620 which had just a small amount of rust.
The Summits are fantastic grills. Yes the cookbox and manifold can give you issues, but give Weber a call and see if they can help you out. Good luck!
"fantastic" is a little hard for me to accept in a +$2,000 grill with cheap painted steel cabinetry. I suppose when new they cook well, but too big, too heavy and over-complicated for my taste.
