Other than the obvious vent,what is different from a 2013 Batwing fairing versus a 2014-later edition? Is the curvature different? Is there a difference in width? Between the bolt holes? The reason I ask is their windshield trim is different,somehow,at least according to the part numbers and application. H-D has some new windshield trim for the 2014-later Batwing that I would purchase for my 2011 Street Glide,if I thought it would fit. Has anyone ever measured the differences?

 

Three bolts are spaced differently

 

windshield bolts spaced different, think the bolt on pattern is to, i know the bolts are longer, but not %100 sure, has indents {formed differently] for air flow
