I know how to fix your sagging rear fender. Cascade innovations sells a bracket. But if you want to go the free route, like I would. I've done this many times and it also takes out the white marks you get from bending the plastic. Propane torch. What you want to do is prop the fender up with a piece of wood or somthing similar. ( it helps to get a piece longer then needed, in other words make it a little taller, because they will sag a little ) Then heat the fender from the bottom side untill its about ready to melt. Try to heat it evenly as possible. Then just let it cool. Its easy and quick to do.
