Looking at purchasing 17" Memphis Slim night shades black; a couple different sites have different info. Believe I need the 9" headlight opening for my bike which should cross to MEB 4221 but not sure about the trigger lock mounting kit? Again one site says MEK 1914 (for black)? Three sites I have looked at, all have part of the information but not the exact fit for my bike to include your site? Will the windshield MEB 4221 and the mounting kit MEK 4221 work on my bike?
