Wow, this was worse than I thought once I started cutting. The drivers side was worse so I'm knocking it out first. The bottom 4 inches of the B pillar was gone as was 1/2 of one of the braces and the inner rocker. It looks like someone had put a new outer rocker on right over the old rusted out one at one point. So I didnt have to remove the old rocker, it just fell out on its own once I started cutting. I'm not fixing it all right now; just building a structure that will support the floor and give me something solid to build from if I decide to go back later and go further with it.
