Hello, I have a '99 TJ and I have a lot of rust underneath but it's still rolling along just fine and for us, it's almost always a jeep for the trail, and the woods. The skid plate under the gas tank was so rusted that it was falling off and finally, I tore the rest of it off manually. Now a few weeks later the gas tank itself has dropped down a few inches. My question is how important, or necessary is the skid plate? I found metal gas tank support straps specifically made for Jeep TJ on Amazon...will these do the job? Thanks for your help.
