A friend of mine's front driver's side quarter panel (a.k.a. "fender")
became dented in a parking lot hit and run. Her car is a 99 Civic LX.

Has anyone replaced one of these quarter panels? How much time did it take?
Where are the main fasteners?

I am going to dig for a manual but am not optimistic I can get my hands on
one.

If this were my car, I'd wing it. But it's someone else's car, so advice
would be appreciated.
