Is this a Ws6?
WS9 is the Formula conversion code and does not mean the car is or ever was a Formula.
It means the vehicle is a V8 equipped Firebird and therefore all Formula's and Trans Am's will have this RPO.
W66 is the Formula RPO
Y82 is the Trans Am RPO
WS9 + W66 = Formula
WS9 + Y82 = Trans Am

I thought the WS6 was like the Bird version of the SS, if thats true what does a formula have?

The easiest way I find to explain the models is as a progression of added options.
A Firebird is the base model V-6. A Formula is a Firebird with a V-8.
A Trans Am has a different body package with up-level wing, different nose and rear end etc. And the WS-6 is an additional package to the Trans AM.
I know there are finer points to the explanation, I just find this the easiest way to explain it when someone asks me.
