written with MORE detail then I normally write TECH articles for the site for the non-Z owner to be able to work through (the alignment speciallist). The instructions really cannot be much more clear unless I videotaped me installing the thing myself. That's way overkill for how simple that thing is to do for the average person that works on cars professionally. The instructions are adiquate. If they are scared of the instructions you probably don't want them touching your car anyway.
Take it to either PS, or a collision center and be done with it please.
