1991 was the change over year for the location of the SPID label. Early production has it in the center console glove box, late production will have it on the lockable storage compartment lid on the left hand side of the trunk area.
It will have the RPO codes for all installed parts and options. Axle ratio code will be in the Gxx series. That will tell you what ratio the car was built with. |

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.
