Back in the garage this morning and made a little progress. I was able to cut the passenger side rocker panel out. I tried to test fit the replacement rocker panel into it's spot and wasn't able to fit it in place. It looks like the running board will have to be removed to make room for the rocker panel to be put into place. I've always resisted removing the running boards because I thought that the running board brackets would be knee knockers. However, it looks like I don't have a choice. So that will be my next adventure.... I've included a pic of the old rocker panel and yes, that is the bottom of the hinge pillar still attached to the rocker panel. It was rusted all the way across and had already separated from the top of the hinge pillar. Now, it's out of the way!
