Just looking over the family tree and you're missing the Willys Jeep Utility line- the Station Wagon and Pickup. These would be the fore runners of the Cherokee, Wagneer and Gladiator. The FC 150 and 170 was a Jeep all on it's own. Other than sharing the same frame as, I believe the CJ-6, it basically has no forefathers and no descendents. DJ's were two wheel drive. I have an original Jeep ID poster, I'll see if I can get a good picture of it if you want.
