I have located an older style Weber Q and wanted to use it with the take-down cart, however, its legs are different. Has anybody successfully modfied the legs on one of these to use with the newer cart? It is 2008 but it like new condition Q 120? Can I transfer the new-style legs from a 2017 Q 1400 to the older Q 120 or will there be some snafus? My plans are to actually acquire an additional 2200 that I can use with the cart as well (that came with the Q 1400. Maybe I will just try it and report back... Lastly, is it worth upgrading to the stainless grates?
