Has anyone changed out thier windshield on the second gen corbin ferring? Im trying to figure out how to messure it or should I say where to measure it from. Corbins site says FLHTC wind shields are the same. Thier sold in 6,8,10... inches . since the corbin is not straight across the bottom not sure where to measure from. This one is to cool but only in 6 or 8 and the best I can guess is the corbin is around 9.5 or 10 and I would like to go 1 inch higher then the stock corbin.
