I beat on my stock gas tank skid and never had a problem. I used Kevin's Offroad (KOR) steering box brace and never had a problem. You can also step up to waggy steering box that has a fourth mounting hole.
I'm pretty sure mine gas tank skid is a skid row skid and it's pretty beefy, I bought it off of goofy and between me and him it's taken it's toll on rocks!
