For the rear axle another way to get a 9.5 differential, factory disk brakes, and a full floating axle besides a diamond is to have a housing modified. Here is a thread I found on pirate
http://www.pirate4x4.com/forum/showthread.php?t=585339 He is using long side shafts and modifying the short side for 67" wide. Using short side shafts, modifying the long side and running 1.5" wheel spacers should be around 60" wide. This would be much cheaper than a diamond housing.
