73' B3 340 Duster pro touring build

Oops! I was talking about the AAR hood in the pictures above.

This hood is very interesting and if I saw a picture of it with no
other information whatsoever, IMHO I would have guessed 1968
Mustang/Shelby or Torino/Cyclone (maybe that's what it is???).

Yep, right again The picture was there there just to show the vents that can be purchased and added to any hood but they are shown on a Mustang hood. I knew what hood you were talking about I just added the Mustang Pic to show the vents.
