As some of you know, I am the rogue 360'er that is running CB450 carbs on my bike. I am almost 100% certain that the intake boots are from a CB360 (16211-369-000) rather than a CB450 (16211-283-000) since the inner groove inside the boots snags the spare set of 360 carbs I have but not the 450's. Can someone with a 450 measure the distance between the origins/centers of the two mounting screw holes? I want to see if I can just buy a set to bolt on the 360. I figure that the 450 boots will provide more of a snug fit for the carbs.
