On the side stripes the top of the bottom stripe follows the body line and tapers . The front of the stripe at the back of the fender extension is centered on the body line.
I installed many of these at a mopar body shop years back and would copy the original stripe on the unrepaired side of the car. I to have a demon so I have taken pics of stripes with measurements on many original paint demons. The best pic that I have seen on here is the one below. Do to the faded original paint on the car the rear body line is easily seen.
If new AMD quarters were install on the car or any quarter work done where the line is moved. The best way to locate the stripe is the top of the bottom stripe at the gas cap is aligned with the top of the gas cap handle. I have seen many of these stripes installed to low and they use the remaining part of the stripe on the cap. The caps were painted stripe color from the top of the handle down from the factory . Hope this helps.
Also I want to ad that the original stripes when purchased from mopar. Had the gas cap cut-out all ready cut in the left rear stripe. Unlike the repops they could only be installed in one location. And not confused from side to side. I also see many demons with the stripes on the wrong sides. They are different having different arches and widths on top and bottom.
If you look close at these cars you can see the top stripe has more of an arch behind the door. It starts out narrower but gets wider. Some repops do not do this they are the same top and bottom. Chose wisely when purchasing your stripes. I do have more pics with dimensions shown.
Note: The stripe does not continue under the gas cap opening. It just reaches the edge.
