I purchased a Webber at an estate sale for $100 and I am in the process of refurbishing it...a 1996 Genesis Platinum II, similar to Jeff MA' s unit, which he posted in July of 2016. I'm not doing a total strip down but close. My question is, should I buy one set of S.S. grates for this unit and not install the smoker box which sits on the left side. Or buy the S.S. grates and cut one side so I have a small section I can remove when I want to use the smoke box? The porcelain grates are too gone to cook on. Any thoughts would be much appreciated.
