67 firebird rear question
I have a 67 firebird housing that has a large "N" cast in the cop of it. Is this for nodular like for the ford rears? It is a dual traction bar rear that had the HD 4-pin posi and 3.55 gears.
I have had other dual t-bar rears that didn't have the "N" in the past.
One person told me the "N" housings were only used in the 400 CID 4-spd RAM AIR VI cars.
I don't know anything about pontiacs and am trying to determine if this is a special rear or not.
Thanks in advance for your help.
Eric
