a SPOHN torque arm. The one that has the end bushing as part of the crossmember.

I believe the steel one is getting over-spun when you
move up from 2.73s (where it was "good enough") to
3.73s / 4.10s, that may just be beyond the quality of
its balance or resistance to bowing. That would whip
the hell out of the tailhousing. I figure there's a good
reason GM put the aluminum one on the higher-rear-
end-ratio cars, being as how they love to spend the
extra dollar. The group of people who break tailhousings
on the dyno, seems to have too high a proportion of
steel stock driveshafts. But I don't know that there's
any "undeniable proof", just an observation.
Aluminum ones seem to go pretty reasonable, used.
If you're really hardcore, maybe one of those "nitrous
ready" super strength ones and the best balance job
you can option.
