posi rearend needed limited slips keep braking

I seen a few 7.5" rear axle assembliesHowever the real problem could be that the axle housing is built too light and flexes under load and this in turn causes breakage.

Yes. I've got a pic of one around here somewhere from my old cam.
If I can find it, I'll scan it and post. Too much traction and a little too much torque busted around mid pinion. Scared me, didn't know what happened.
