As a Grand Wagoneer ZJ owner, I think I can provide some insight. They do have the tufted leather seats, and what I have been able to find is that they are just Limiteds with woodgrain and different badges. They were only available with the 5.2 V8 and I'm pretty sure the 249 T-case. They were only built in 1993 and were introduced midyear. There can't be too many built because of it's introduction date and the fact that Jeep stopped making them after the 93 model year.
