Thats cool thanks. I also need to know how you measured it? or what the best way to measure the blower to clear the hood you know what i mean? i dont want to be too far off to one side and not far enough on the other or make it off center or something? i measured it out pretty good with about a 1/2" all the way around but before i cut it i want ot make sure i measured it right before i go and cut it.
