Just like on the passenger’s side, I had to make a few patches to the inner rocker on the driver’s side. Nothing too drastic, just cut out the areas with a cut off wheel, cut new pieces out of 14 ga. to fit, and welded them in. I wasn’t quite as thorough with some of the rust and patches as I was on the passenger’s side as I was trying to get it done. I just did the worst areas and cleaned up the rest. The inside of the rocker didn’t look too bad for the most part, a lot like the passenger’s side.
