Where the stripes on 70's Z's flat black or glossy black. Thinking of putting racing stripes on want to make it look as stock as possible.

Which "stock" stripes are you referring to? My '71 had/has none.

There is no such thing as a stock racing stripe on an American import HLS30. Side stripe kits (decal) were available as a factory option for Japanese domestic S30s and S30-S models. I suppose one could get them on a PS30 also. That stripe kit (stripes along the lower fender and door) was eventually made available in North America as part number K3110-00010, 11 and 12 in red, white and black respectively. I believe it is part of the 1972 model year listing of dealer installed 'options'. The only stripes that would be considered stock on an American import model, would be the black pearl or Zzzap stripes.
