Is this the part you're looking for?
If so, no they don't make one for the Pontiac. They make one for a Chevelle but it is way different. You could make it work but would be tons of time/money. Your best bet is to find a car to cut up if possible.
I know easier said then done! Sure as heck once you get the Chevelle piece and modify it to fit, a car will come up to cut on!
