Welcome...beautiful looking car. Yours may be a Special Wishes car done by the factory. The early ones did not have the slats on the front fenders.

Is the car fully stock? If so regular bolt ons, like exhaust and muffler. Go out and enjoy it the way it is now, once your small issue has been resolved then plan out your upgrades. I always say to start out with the suspension first then move on to extra power. Elephant Racing and Rebel Racing offer mild to wild suspension upgrades.
By the way...more pics when you get a chance
