tabetha you are mistaken. i am not surprised that a 7" diff didn't last long in 2wd configuration. if it would handle the torque, why was a 7.5" fitted in the first place to 2wd's (and even scorpio's)?

shanemc don't bother with another 7" diff. put the 7.5" 2wd beam in. straightforward swap. swap the 4x4 vented discs over first though

polybushes can be used for beam mounting, but not semi-trailing arms on 2wd. they should have a special bush in them
