These are brand new parts that up until now, were no longer available. These will fit all production years for the 914. The "Early Cars" (in this case from 1970 into 1973 and including the 914-6), had the White Surrounds. The "Late Cars" (in this case from somewhere in 1973 through 1976) had the Black ones. It is not uncommon to find early cars now with the Black surrounds on them because people would paint them black or swap them out with black ones that don't show all of the dead bugs sticking to them.
