70 Darts used a one year only exhaust tip. It is not the same as the b'cuda tip, but that is what Accurate will sell you as correct. I have had this discussion with them for years. I even gave them a rusted factory tip that was correct so they could use it to produce a correct tip. They say that the stainless that they can get is not thick enough to produce the long box on a correct tip. I will post pictures of a correct factory tip, a reproduction correctly shaped tip that I got from Stainless Steel Exhaust Tips in Florida and the Accurate tip. When Accurate started producing the tips they offer in large quantities it put that small Mom and Pop business right out of business.
