Welcome CMNYC,
thanks for posting the pics and serial number.
Starting with the 1987 model year Giant changed their serial number format for all the frames they manufactured.
For your serial number:
G = Giant manufactured
Z = when in the year the frame was manufactured. Z is late in the year.
8 = 1988 the year of manufacture.
The decals on your bike are for the model year 1988.
