Almost done. I just have to go find a longer pos cable so that I can use the engine block ground. Hopefully Kragen's or Auto Zone carries those because Sac. Mustang doesn't. The Sac. Mustang guy said that grounding it in the truck works fine, but I have serious doubts and I poked around on similar topics and found others who tried to ground in the truck with poor results.
Other than that, all that's left is to undo a few bolts, pull the old battery mount from the nose and take some pictures.
Then I get to drop another $500 in parts in the front suspension of course, yay.
