There is a recent aero-cap thread where wood slats were used. Seek it out, I might be able to find it. I'm mentioning it because he said he made a slight mistake not following the template true which no one else could see. You don't want to make the same error, apparently it is all to easy to make.
I've done over a hundred of these overlays, and I have to say an issue came up today when doing one for you.
I'm hoping Aerohead can make a clarification, it's a real puzzle.
Part of a photo Aerohead posted recently, flipped 180- degrees and given an Aero-template overlay. Oh yea, ground plane was out of tilt by 1/2 degree - fixed it.

The pink vertical line isn't supposed to be the line-up mark, but that's how it came out. I think we are supposed to use the yellow line, but I've seen people use the middle point of a flat roof (
orange line). I wish I knew what to tell you.
Anyway.......... you have an extended cab, the 3-door, right?
This is the most conservative use of the template shifted all the way back.
This is the middle point, which I see used more often.
Base image so you can try your own.
There are slightly longer and shorter versions of the aero-template floating around, I use this green one just because I like the color to be honest. I think Bim-Bow-Blam or something like that made it up for the sticky thread at some point in time.
