Roof supports for my 2016 60th anniversary ( 2HC-K831A-00-00 and 2HC-K831E-00-00 respectively) are ordered, but on back order with an eta in late November. I will place a WTB listing for some used ones but need to know what other, if any, roof supports are compatible. The pictures in the parts listings all look the same for 2016 through 2018 but I realize that subtle differences may not show in those pictures. Do the differences in the base part number for the roof supports just indicate a color difference? I prefer black but for now, any color will do. I need them to be exactly the same as what I have. Does anyone have real world experience they can share?
