Does all the 300zx has t-tops?

Most of them do. The ones that dont are called slicktops, and are rare

dont forget the convertable. There also fairly rare but there out there.

since we are on the subject of t-tops, thought i would share this, i want them http://twinturbo.net/net/viewmsg.aspx?forum=general&msg_id=1263246

Slicktop's were produced from 1990-1996. 85% of all 300ZedX's were T-Tops, (Slicktop's proper name is standard roofing) and 15% were standard roof.

Slicktop's were 350lb's lighter, due to; of course, there was no need for the lower end of the uni-body to be reinforced (because there were no T-Tops). If you ever get your hands on a Slicktop's, get a Twin Turbo powertrain, makes for a very fast car.
