OK, if you really want this right, here are a few more tips:
1) There are 4 pieces to the stripe on each side: scoop, door, fender and bird, so you have 8 total pieces in a stripe kit. The stripes pieces are NOT INTERCHANGEABLE and
are specific, side to side. The bird sets the pattern for the stripe, then separate the pieces left to right.
I can't tell you how many stripes I see where left and right pieces have been put on the wrong side.
2) OK, life is in the details. When you install it, don't just slap the pieces on there. Look at the picture below and see the pattern made by the little "x" shapes. I made sure that pattern continues across the door seam; the distances between the little "x"s are consistent. This is not by accident! You have 4 seams you need to deal with (front and rear door seam on each side). Make sure the pattern is consistent across each of them - it will make the stripe look better.
3) As stated above, be sure the stripe starts at the correct spot in the scoop, centered on the road runner script (assuming that was put in the correct location). I suggest using blue painters tape of the same width and lay a tape "stripe" down on the car so it is straight and in the correct location. Once you have it right, lay two more tape lines tight above and below your tape "stripe". Now remove the center tape "stripe" and you have a nice guide for laying your stripe down.
I have put quite a few decals on, and this is one of the harder ones. The pattern is part of it, but it is hard to get it really straight since it is long and thin. Look down the stripe from the front of the car and from the hood scoop - this is much more effective to see how straight it is than simply looking from the side of the car.
4) make sure you have a good transition between the bird and first tape stripe. Again, look at the pattern and plan this out before laying the stripe down.
5) I started with the bird and worked my way backwards. Don't ask me for "correct" measurements of where the bird should start (i.e. how far from the front of the fender). From the research I did, it seems this was not consistent as these were slapped on by a worker fairly quickly back in the day. I simply chose a spot that looked consistent with most I had seen. Perhaps
@dadsbee picture shows this, but I can't read it.
Your reward for doing all this right is that people won't notice all the little details (but they will if they are done wrong)!
Good luck.
