I've built a steel strap/ clamp for my front third. It's made of 2"x1/4" steel, and mounts to the crossmember at the original mount, wraps around the output shaft area of the case, top and bottom, and bolts to the cross member above the pass side a arm, clamping down on the case as it is tightened down. All the edges are champhered to prevent any stress points. I've been running this set up for a while now, and it seems to work great. I have an ARB in the front and was worried about the extra stress on the housing. I could'nt get my hands on all the steel parts for an upgrade, so I made this to tide me over. So far so good. There are photos somwhere in the archives of this.
