Hmmmm, that's kinda rude. They have detailed instructions in their catalog, but if you don't have one of those, I guess you'd never know. I didn't get any instructions with either of the Ford sets I got from them. I bought a Chevelle set from them once that had instructions included. I'll make a quick scan of one of my catalogs and post the details here in a bit. This is not my car, but it's a good pic.
