no, no Z ever came with a sunroof form the factory, the curve fo the roof does nto lend itself to a sunroof, they have to distort the metal to put one in which si why most z guys avoid cars with a hole in the roof (FYI every factory sunroof I've ever seen has drain holes in the corners beneathe the glass with tubes that run down and out to help prevent leaking aftermarkets do not do this), at least you got a solid chassis, rust free simply doesn't exhist in my area, congrats on the find
the manual conversion is very simple and if you plan on an rb swap you might want to just do it then
I'd keep my eye otu fro a 240 hood btu thats a matter of taste/origionality, the mirrors and armrest are also add ons
and I LOVE the licence plate frame "Do it in a Datsun", words to live by
