Another paint code that was most likely used on some 914s is L67Z "Police Green". Used on german police cars during the '70/'80/'90 ...
I was able to verify that that color wasn't available until '74, thus i was able to narrow the possible date range to '74 - '76 ...
With that info, i added the color to the main list of colors.
Now all we need is to get our hands on a german police 914 ...
