Rocker Panels

The other day my car was hit and the side of my car slammed into the curb. My passenger side rocker panel was smashed in several inches. My question is, how can you replace the panel, if at all? Thanks for the help

it has to be cut out, I don't think they "unbolt."

thanks for the reply. so can i get a replacement one from somwhere and would they have to weld it back on?

To do it right the car will have to be put on a frame machine to hold it straight while its changed. The rocker panel along with other panels behind it is a major structural piece. How bad is it? Got pics?

i can try to get some pics this weekend, its pretty bad. the panel was pushed back about 3-4 inches. thanks for the help
