Did you made those doors yourself or you bought them? Whats the name of this kit?

Nice looking car.  I've got a 1977 with the exact color scheme.  I thought mine was in good shape but your interior has been taken better care of.  I want to keep mine as close to original as possible but I'm having a heck of a time finding the off white interior for it.  Most came with the black interior unfortunately.  Best of luck.

What a great name for your Z.
