Cheers guys - These old Summits are just awesome!
Unfortunately its one of very few models that Weber really doesn't have that many parts for anymore. You can certainly get them up and running with generic parts like burners etc but some of the more vital pieces just aren't available. That's what started me down the path of the prep cart which I absolutely LOVE! The trick is finding the model that came with the stainless lower shelves instead of the enclosed cabinet style. That way you just slap them up top and more or less have a finished cart [emoji106]
