I have a set of (4) 7" flares for a CJ. The rears however are TJ stlye. The have the usuall mud dirt and scratches from branches, but besides that they are fine. If your tires stick out a ways these will keep shit from flying all over. Also, if you ever break one you can buy replacements 1 at a time.
Here is link to a new set to get an idea.
I can get pics, but not until sunday at the earliest.
