Its def. a gx. Natural gas (propane) I think they were 98-2001. And if I am not mistaken (which I often am!) its a factory forged piston with a 12.5:1 in the gx motor. It has a rather large dome. I don't even know if they were available to the public--only to fleets, like rental car companies. You should IM Mr. Bone--he would know.
