So, just a stock 8.5" open rear? No specific gear ratio? No posi, correct?

Have '73-77 8.5 A-body bolt-in axle core rears in the racks.. Have built up a couple dozen of the '73-77 A-body style. most did not come with good gear ratios & a posi. Not a fan of the c-clip axle version
of the '73-77 A-body rear, though may have a housing in the racks.. Original 28 spline "S spring" posi's typically show wear to the clutches, & some units have side gears w spalling (pitting). Going back 30 years, I always replaced the clutches & properly shimmed up the side gears. Not easy to do with limited avail of correct clutch side shims. The clutches have been reproduced for the last twenty years, but they are expensive. Just something to factor in if you stumble into what will typically be an expensive core to have gone through.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
