About how much wider is a dana 60 front axle (wheel mounting surface, not with wheels/tires) than a toyota front axle ? What I'm wondering is can you keep the toyota rear axle without the front being too wide. Maybe the 60 can be narrowed a little? I'm sure there is alot involved in doing this swap but I have never researched the details. maybe its time to.
If it is really so strong, It is a worthwhile upgrade...
