A friend of mine had a light blue #s matching 71 340 Duster 4 Speed back in the day. He modified the original 340 heavily with 11-1 pistons and a roller cam. He painted it In Violet FC7. Six pack fiberglass Hood and centerline Wheels. He didn't abuse the car (too much) but it looked nothing like it did originally after he got done, he sold it sometime in the mid-90s.. it's still around I believe.
