Thanks for the response mickmate. That was my original reasoning---if the lower control arm mounts could take all the stresses of the control arms, then surely they must be up to the task of taking the torque from the engine. What some of the other posters were saying, however, is that the differential casting itself will just crack like an egg with all that force fed into such a small area, as opposed to be spread out throughout the casing. What I still don't see is how solid mounting from the bottom is any narrower a base than solid mounting from the top (in both cases of course, doing away with the original sub-frame cage). It seems to me that there isn't really any difference...but then again, I don't want to be the first one to try, and find out the hard way with a destroyed rear axle...Surely someone must have tried this before?
