WTB 8.5 rear axle for A body
 

Looking in the Southern states -

What year? They changed in 1973. Thanks, Bob.

Looking for direct swap into 69 GTO project.

I have a nice 8.5 from 71 F body - if anybody wants that -

Shipping from/tp N. Texas area

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

Correct

I have a 1972 Olds, but I'm in NH.

Do you have a Fastenal store convenient tp you? I've shipped rears with them in the past. Thanks, Bob.

I believe you will need to shorten your driveshaft about one inch.

I may also have a driveshaft, depending on the transmission.

Yes, I use the one in Bridgeport Tx

I'm looking for and 8.5 posi a-body 1975 28-Spline

i have a 65 chevelle 323 non posi dif in oklahoma. been blasted and painted. being pulled out for a 9".

I have a driveshaft for an th400 and a 8.5 in KS

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.
