I don't have a template off my 71 Challenger RT but when I put quarters on it back in 1992 I measured my originals and wrote it down on my notes. I can tell you this worked well on my challenger, From the open door jam the top of the scoop is 1 inch back and 1 1/4 on the bottom. The bottom of the quarter scoop is 1/4 above the style line which is not very pronounced. I took a picture of my driver side but not sure how much it will help,
