Definitely 3.73
and posi and 12-bolt and multi-leaf, and Factory rear stab-bar setup. and drum brakes. Not certain of 1973 anymore........might have been any of the 1970-73 Formula 400's with 4-speed and fancy open-scoop hood. |

A friend had a 70 Formula 400 4spd with the 12 bolt original equip.Back in early 70's there was a rumor GM Pontiac (canadian)made a 10 bolt with 12 bolt innards never could confirm.My SD doesn't have a 12 bolt and 2 others I know of don't.A 71 TA I worked on in 75 didn't have the 12 bolt.

The 74 SD455 T/A that I owned had a 12 bolt 3.55 gear put in by the original owner. Oh I Wish I had kept that car.

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.
