So recently bought a 2003 2dr blazer LS, 4WD. Pretty good shape. One thing I noticed is at the rear of the back wheel well liner it looks like there's a missing piece? I can clearly see the leaf spring , where I would think the liner would cover it also noticed two empty bolt holes where some form of cover would be bolted to save the spring and other assorted underpinnings from being ravaged by salt during the winter months (yeah I live in the Salt belt, Canada to be precise) anyone know if there IS something that supposed to be attached there?
