I would cross post this on the Weber Gas forum. There are lots of guys that rehab gas grills and someone might have a spare rack available for you. I don't know if they all monitor this forum. https://tvwbb.com/forumdisplay.php?91-Weber-Gas-Grills
You can purchase that rack new for about $60 online, but I know that is a bit expensive. But, it is an option.
Good luck,
Bruce
Yeah, I found it on ereplacementparts but the price is too steep. It really isn’t a required part, but I’d like to restore the grill to like-new condition. Hoping someone has one laying around, maybe that needs to be refinished or the like.
