This may seem dumb or even a little late to some of you. But I have never actually really dug into my car other then what the VIN tells me. Pontiac,Trans Am,Sport Coupe,400 c.i.d,4-bbl V8,1978, Norwood,Ohio car. How do I go about finding out if it has the WS-6 option or w-72 or whatever else I can. I would be just looking at the body of my car. The motor is like 20min away but I might be able to go get a look at it this weekend. I just want to learn more about it. Thanks.
