Which to replace first?

[Knight72]

Hey guys, I'm finally starting on my fist C10 rebuild after getting my rough draft plans together on where I'm headed on this build. I've got some pretty serious areas that need work and I'm trying to pick the best starting point. The cab for sure needs cab corners, kick panels, and rockers. Which panel should be replaced first? I was assuming the cab corners, kick panels then rockers, but I wanted to get some confirmation or corrections before I start. Any insight is helpful, thanks all.
