The one pictured is what I have Tim, measuring outside of the edges of the bracket it is 5 1/2 inches and it puts the holes way out of alingement to the bosses on the manifold and runs just passed a 2 hole boss that the horn bolts to, I'll try to get a decent picture of it today, and doesn't touch the manifold except where the half round portion of the mounting is, it doesn't even come close to resting against the two raised bumps.

Thankyou
