I took the day off work to work on the truck for a few hours and hang out with the wife and son.
I have looked at diagrams showing the side skirts but wanted to know exactly how they were attached; since I need to do rockers anyway, I figured I'd take one side off to give me more room to clean up the frame. Those brackets didn't want to come off; all the bolts were rounded off and rotten. I had to cut out the inner rockers around them to get them off. I think I will be spot welding them onto the new panels when the time comes because I don't have a template of where to tack weld the nuts to the inside of the inner rockers.
Inner and outer rockers won't be bad too bad to do. I fear getting the pillars to line back up without sagging but I'll figure it out. I think I can clean up these side skirt brackets/plate and reuse them. Now that I see how the steps attach, I'm comfortable keeping the steps mounted factory style (I was going to build brackets and bolt them to the frame rails).
I cleaned up a few body mount cups and frame mounts but didn't get anything primed because of the humidity today. I also decided I want to cut out the lower inner rear wheel wells and build new ones. I see a major GM design flaw with them that I don't like; that seam is bad but the inside is foam filled along the seam and retains moisture. It will also allow me to prime and paint these inner panel areas too.
