there is nothing to hard about it. Are you keeping the stock gears that were inside it? If no then it gets a little harder depending on your skill set. The trac loc is easy enough. The gears shouldn't be to bad and you can probably reuse your stock pinion shim if you are planning on the 3.55's mentioned in your sig and they are ford gears.
Always double check pinion depth, gear pattern and backlash though. Have you looked at some of the articles on it?
