Hello Todd5050,
welcome to the forum.
The serial number is for a frame made by Kawamura. The first character "G" was used by Kawamura to indicate the frame was intended for a market in Asia. The "J" is for the year 0 or 1990. The frame cannot be for 1980 because Kawamura was not making MTB frames in 1980.
