I finally managed to round up a set of rocker extensions for my car. I was looking at them to see what was needed to install them. I see a bunch of clips on the upper edge of them so I guess that I will have to drill holes into my rocker panel for those. If that is the case is there something (double sided tape, silicone?) that goes around the wholes to help keep water out of them so it doesn't rust the panel out from the inside? Also I see the studs on the end that go into the fender, so I drill holes in the fender for that. And then my last question is the what hardware is used for the big holes in the front on the bottom, and what hardware is used for the little holes on the bottom? (guessing....bolts, washers, and nuts on the big ones and rivets on the little ones?) As always, thanks in advance for all of your thoughts and help!
