Ok, I found the pics.
There are a few things to watch for when you do this:
First, the stripe is made of three pieces (one center for the trunk lid and two sides for the fender extension) that do
not have the correct size for verts. I had never realized that the fender extensions on fastbacks are much wider that the ones on verts and coupes.
So the center stripe will be too short but you can carefully align the butt ends of the extension stripes to the center ones and paste them.
If you look closely, you will see that mine lines up nicely on the passenger side but a little less so on the driver side, That is because the outer pin stripes at the end butt of the driver side extension stripe were not completely parallel to the big one in the middle. Usually that would not cause any problems because that part would get bent around the corner of the extension and go inwards in between the fender and the trunk lid.
In this case it provoked some colorful yet explicit language but eventually I was able to make it look halfway decent. If you blow up the picture you will see the transitions almost right above the clear lenses in the middle of the taillights.
On the passenger side everything lined up perfectly.
Second, the vertical part of the trunk on the fastback is shorter than on the vert which means that on the vert, the stripe will sit higher.
Usually the lower side of the stripe will line up with the body contours but not in this case.
The key cylinder is the reference point here, so you need to work it from there.
Just try to keep it parallel to the edges from the trunk lid and fender extensions to the taillight panel.
