Some neat stuff there, especially the bulldozer. Where are the trails you hike when you spotted these? I've got a few friends in that area who may know something.
That car is one huge mod, and very nicely done to boot. There is no '06 Mach 1. Ford could take a cue from this if they ever do another Mach. Congratulations on the win and a beautiful car.
mounting instructions for the 05-09 kit are here, don't know if yours mounts the same way.
