Here is another link to a lot of information on Dana 44s:
This is a quote on the Dana 44 from Wagoneers:
"Narrow track (Wagoneers, Grand Wagoneers, and some Cherokees) fronts were 58.4", rears were 57-59", depending on who you believe. Wide tracks (some Cherokees) were about 6" wider than that, or 62.5" in front according to Louie Belt, who installed one. Kerry Embry claims narrow fronts are 60.5" and wides are around 65". I personally measured a narrow '82 Wag to be 61.5" front and 58.5-59" rear. The pinion on an '87 GW rear is offset 3/16" to the right. J-truck axles are reportedly about 67" wide. Obviously, YMMV."
The same page states the YJ width as: 60.5" rear, similar front
If you do the math, it appears the wide ones are anywhere from 2 - 5 inches wider than stock. If you run a stock type wheel with 5 inches of backspacing , even with the wider axle, it would probably extend 2.5 inches wider than stock and could most likely be covered with a fender flair. It would not be my choice, but I guess it is doable.
Bottom line is there is a lot of info on the net to help you make a decision. Google is your friend!
