The floor pans inside my US import 1973 240Z are covered with a black mastic-type material. I have been removing it to check the floors as little bits of rust were visible where the mastic had lifted in places. The floors are fine, small amount of surface rust treated and now I’m ready to repaint. The floors are painted a very light green colour. Does anybody know the shade / code of this colour? Also, is this combination of colour then mastic on top typical of all Zs irrespective of market? I have had three other Zs over the years, but this is the first one I’ve had with its original floors!
