It has been about 6 years ago, but I bought the entire kit from Stinger and sure there were some fitment issues but I worked them out. I was very happy with the results. My car was a factory air grabber car but had none of the fiberglass stuff. Heck it was harder finding the attaching castle nuts etc than making the repop fiberglass unit work.
Must have been ok when finished since it won many awards. Even a First in Stock class at the Nats.
