Hey, Troy,
Nice rig! . . . for a Dallasite. What can I say, I was born and raised in Ft. Worth.
If I had a digital camera, I'd run outside and snap you a photo. I began by taking out the window and wing window and front rail (The wing-window has to be loosened before the big window will come out) then decided I would need access to the lower workings in order to locate the bolt holes, etc, correctly. So I cut out a small panel down closer to the bottom of the door. I don't recommend this to all you purists out there, but it allows access to us street-rodders.
By making careful measurements, I was able to determine just where the attachment bolt holes need to be drilled in the inside door panel. Obviously, the track needs to be attached to the inside of the door. (Perhaps your model truck will not have the same openings).
I made sure I marked the center-point of the window (front-to-rear)on the door with a marker to make sure I kept the track under the middle of the window. If you don't take care to do this, you'll have your motive source off-centered, which can induce 'wiggle/wobble' when the window is raised. You also need to ensure the track is square for the same reason. I did not cut the track at all. Therefore, the motor ended up being pretty close to the door bottom (but not touching the bottom).
I also made sure the electrical connections were well protected by covering that area with electrical tape covered by 'pooky' out of a squeeze-tube. On the first try, the front edge of the window was closer to the inside of the window slot in the door than the back edge. I had to carefully loosen all the bolts/screws (I used pan-head screws - note the threads in this kit are #6 metric) and experimented placing washers at the base of the track on the front-side bolts/screws until the window was pretty well parallel to the window slot in the door. I made a final adjustment by placing a washer where the plate at the top of the track bolts onto the window frame support. There's a rubber window-stop where the window bottom needs to stop. The trouble is that it is not centered on the window. This probably doesn't matter with a mechanical regulator, but with a centered track the window wants to cant over slightly when at the bottom. I'm modifying mine so the stopping impact will be near the window's center.
I suspect you'd have to pay attention to this kind of alignment with any kit because different doors have differing kinds of curvature, etc. (I'm still talking about flat windows, here).
Good luck!
