the cowl tag will often have the characters of a base model, and the model RPO code will be a couple lines down.
as an example a 1970 Trans Am would have a cowl tag stamping of 22387 (base model Firebird), then two lines below would be the RPO code WS4 - which indicates it was a Trans Am. I think it was done this way because the cars all started as base models, and as they went down the line became associated with a specific order number.

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.
