Was out in the garage today, my son purchased a new 2016 F6B couple months ago. It sitting next to my 2013 and I notice something different. On my 13 and all other 1800's I have owned there is a plastic trim piece on frame above side cover that covers the large weld. My sons 2016 does not have it. Looked on the internet all pics I saw of the 16 models no trim piece. Anyone know why??
