Please remember, this alignment spec is above and beyond what Ford mandates. If you want to get an alignment to within Ford tolerance it does NOT require adjustable cam bushings. Ford may cover a regular alignment, they are not required to cover one requiring extra parts.
This spec was posted for those that wanted to dial in a much tighter tolerance over and above the very broad Ford spec.
