Moser 8 3/4 Housing... anyone use one ?

I broke a fresh 742, 4.30 8 3/4 the second time my 408 hooked up. The housing is not the issue, it's the case flexing and the pinion gear trying to climb the ring gear. On mine the caps were fine, it broke teeth off the ring and pinion. At the time my Dart weighed 3260# and went 1.38-9 60' in race trim. I rebuilt and sold the entire rear end and bought a Strange S-60. A nodular case may have been fine but I didn't want to take a chance on breaking it and have to pull the transmission apart again.
