Recently bought a 93 foxbody notchback. I took everything out so I could paint the floor pans and also just to check over things. I noticed in the back over what I think is the wheel well there is a piece of metal that looks like a bracket above the right side but not on the left (refer to pics below). just want to know if I need to put a piece back on the left side and why would someone take it off anyway? Thanks for your help
