Ed, this the exact same problem I had with my dana 6.17. My housing was braced with the LPM cover also. As best I could tell the problem was with the teeth on the ring gear. Nothing you could see but the backlash would get tight in a couple spots. I checked everything and had the gears treated and rem polished I think it was called. They looked like chrome when I got them back. This helped but finally I just loosened up the backlash. Seems like I had as much as .010 thou. difference from a tight spot and the rest of the teeth. Not ideal but I ran it and it lived.
With a 6.50 and a auto. in this car years ago I never had a problem. When I started up again and installed a stick the problem started. Don't know if is the gears they make now or me learning clutch setups as I for sure had it way to tight sometimes.
