probably the exact same modifications identified in your article, except you would probably need to shorten the rearend, if they don't suggest it already, but I can't really say.
Why do you want to do this swap? If you have an 8 inch rear already in it, they are plenty strong, and MUCH easier to swap gears in. If you don't have an 8 inch already, I would suggest getting one, or even a 9 inch, over the 8.8 that comes in the foxes.
