I wouldn't mess with a ford 8.8 or 9... I would just use a Tracker rear, cut down, and IFS'd ala Hagen and crew.
I have a brace that has eliminated the reverse breaking of the mounting tab... So an easy foot will help keep the pinion from spitting out of the housing.
I am going to order one in the next couple of days, and probably do a little write up on the install.. if I have the patience... lol..
ACK, it'll be coming your way for the FAQ!
I have been chomping at the bit to spend a few bucks on the Turtle.. and I have finally decided that the best bang for the buck at this point would be $300 for a front locker. Can't WAIT to get it in!
