I have a 2000 Genesis Silver B and want to get a spit rotisserie for it. I have found two models but I'm not sure which one fits. The Weber 7517/9890 (not sure if both numbers are for the same part) appears to be the correct one but I also read that it may need the model 7572. Does anyone know if the 9890 will fit. Is it the same as the 7517? I wasn't sure if the models are interchangeable. I called Weber and they had no idea which one to get. The BBQ has a 24" wide box.
