The problem with that is that type of breakage is catastrophic on the trail and you're not driving it until you get a replacement shaft. There are ways to get a Jeep off the trail, like back to camp for repairs, but you can't drive home with a broken axle shaft. Either buy a left and right rear Dana 35 axle shaft and carry them as spares (they are different lengths) or upgrade the Dana 35 with a Super 35 kit before it breaks.
This is what happened to a friend of mine while we were wheeling a couple years ago. I always thought she had a Dana 44 in the rear or I would have had her drive my Jeep instead of hers on the trail we were on. We weren't able to fix it until the next day, after a 150 mile round trip to get her a replacement shaft.
The first photo shows how you have to hold the wheel in once the shaft breaks, otherwise the wheel will slide out of the axle housing as shown in the last photo. The second shows her the next day after we finished getting her Jeep drivable again. She wasn't smiling much before then.
