Yep, I've seen a BUNCH of different replacement configurations, as well as some variability in the textured green production line style (graphics varied) but anyone doing a serious car won't want anything but an NOS green textured example. For a driver a reproduction textured green unit is what most others want. I don't know why anyone would want a RWB (or other replacement style) filter on thier car unless they had a 72 and later car but opinions vary on that one.
