'93 was the first year of the ZJ and early in production they had the AW4. But those are rare birds now. I had one. Anything prior to '93 was the Grand Waggy with the same body style as the Grand Cherokee. Don't know if was same designation of ZJ or not.
Thanks for the correction on 42RE. That's what I meant. That makes it even worse. Still crappy and weaker.
