Auto body repair & detailing: large dent, fender, good luck

Question
Im thinking of buying a 1982 f150. It has a good size dent on the passenger side. Theres a link to a picture below. Would it be possible to hammer from inside the body to pop the dent out? I know i havent given much info, but any help would be greatly appreciated.

Devin,
       I seen the pic. That was excellent, thank you. Save yourself some time and work.
       You can purchase a aftermarket fender for this truck for around 70.00.

       This is a New Part and up to OEM specs.Check them out on the web.
