well with the new tach the windshield did not fit. I looked at custom building a new plate but with the aluminum billet and time I was looking at about $300.00 with not really knowing the whole outcome of structural soundness. So I called Wind Vest who originally built the windshield mounts and brackets for Big Dog Motorcycles. They actually still had a couple of 1" extension pieces for what I was doing! So I got a set for $100.00 and they work perfect. My windshield clears the tach by 1/4". BTW, Wind Vest said these plate mounts have become rare and very very expensive. They went to a handle bar mount about 5 yrs ago. Something to do with to costly to build base plate.
