camarotale got it right, you can also find it on the net and check
to see if your housing has small ears on the bottom, GM recommends
this one for rebuilding for torque, if no ears on housing, keep in
mind GM considers the no ears inferior. just check for yourself.
if you use good inners, w/beefy axels, it can take some abuse.
good luck buddy, and eleminate the "c" clips :wink:
