LMAO, just bring a skinny friend to get under there with a 12mm wrench. I had access to about 4 of them about a month ago. After I moved the rear back 1.25", I had to shorten the aluminum Crown Vic shaft 1 7/8" and everything slid right in. There is a place on car-parts.com that will sell you one $80 shipped. I did not need to re-balance either.
