I installed the WGA today, and I ended up leaving off the top heat shield when I put the car back together. Its winter and much cooler temps, and I might find an alternative such as a heat blanket when summer heats things up in Houston. That top shield is stupid to remove, and I want easier access to the WGA and to monitor that the preload settings don't move from where I set them today.
Picture 1 is the WGA and with preload set per Adam's video instructions. Adam was kind and responded quickly when I sent him this picture and asked if this looked like it was set up correctly. He said that it looked great.
The other photos are my solution to the metal clips that Ford supplied to secure the two pieces of our cowl together. I drilled a hole through each of the 12 (total) plastic tabs that was just big enough to run a zip tie through, and then I secured it all together once completed. No more clamps tearing at the plastic and IMO this is thumbsup and easier to remove.
