Ok, so for the 92-95 atleast, possibly 96-99, have a rubber piece between the body and the bottom of the fender. It has a piece of metal inside it, which rusts when the rubber breaks through.
Anywars, having replaced a couple fenders in my day, this piece is always trashed, rusted, squished, etc. I have always wondered if there is a replacement, and one day while at advance auto parts, I found one.
It is an exhaust hanger
It is about the correct thickness, all rubber, and should hold up well. Only thing is it needs a hole drilled for the second bolt to go through. Used it tonight and it works good.
Also should help reduce the chance of rust if the metal piece in the rubber has started, but the body hasn't.
I will be doing the other side of my car tomorrow.
