Fairlady Z L20 with tripple mikuni's Share https://www.classiczcars.com/gallery/image/13396-fairlady-z-l20-with-tripple-mikunis/ More sharing options... Followers Can anyone identify these velocity stacks? They are very interesting and I have never seen these exact ones before. Some of the rally works Z's had similar ones with the mesh screens, but they seemed to be more of a cone than these.
