Seatbelts would probably help these guys!
Really most 80s and 100s I see in the boneyards have been rolled. Usually highway speed rolls which is much different than a trail roll. Most of them survive fairly well.
Engineering a cage in a 100 would be a lot of work considering you'd need to plan around air bags. And the late models with curtains would be even tougher. I wouldn't want to sacrifice those safety devices on the highway for a cage that would help on the trail.
