Remove side shell for dent repair on GE Gas Range/Oven

There is a gas range/oven I would like to buy. It was dropped and digital display was replaced. Range works only it has a big dent on the side. Even though the side would not show once installed in my kitchen, the dent is big enough so that when looking at the range from the front, you can see the side panel bent slightly. It does not look symetical. I know how to repair dents and work w/metals since I am an artist. How do I remove the side wall? Is it difficult to remove the side wall (shell) of a gas range? Do I have to disassemble the whole range to get the side wall off or just a couple parts and some screws?
