i am in the process of building a Duster with a 511 BB, 727 trans and have a 8 3/4 being narrowed for the rear.


For a BB that would weigh about 3200 I would skip the 8 3/4..
being your narrowing it and do the 9".. I built up a pretty
decent 9" for a $1000.. all new parts but I narrowed it myself
(this was with a new posi since its for my DW car)... the 8 3/4
I have in the race car is the alum center which uses through bolts
and beefy caps.. but now days that center bare is over a $1000
