If the dana 80 is 4 inches wider I wont be able to use it...I guess I will find out tomorrow when I measure it.

That's usually what gets replaced. You can use different offset wheels and still use the D80. My tires stick out a little, but that's how I wanted it. I surely didn't want the dog track look of an original K20 of this era.
