72 Duster twister with the 275 horse 340 engine?

My '72 Duster, that I bought new, had the dust cloud decals on it. My brother in law bought them for me at NAPA for my birthday. We put them on ourselves. They could have been put on anything. Wish they were still available. On the other hand, just because they were not available in the U.S. doesn't mean other countries could not have had them. Look at what all Mexico had.
