Oh well, I had to replace 2 of the bolts, (the ones that go into the factory engine skid mounting holes) because they were too short after using foam tape. The countersunk screw obviously goes on the front, along with a hook-clamp. I also didn't use the little spacing collars they set, they were just in the way. <_<
I'm happy with the skids, but the mounting hardware is a pain, as is the lack of instructions! haha!
Check out the new thread "AC skid pics" to see my setup.
