They are thinking you will use self-tapping lag bolts, such as the ones I used when I installed my stabilizers. Personally, if you can get to the back side of the bolts, I would suggest grade 8 bolts, nuts, and lockwashers. If not, the lag bolts, and lockwashers will have to do. Stainless steel lag bolts are available, so you won't have to worry about them rotting off.
Meddle not in the affairs of dragons, for you are crunchy, and taste good with ketchup.
