The next area I wanted to focus on was the rear door / rocker box area. This is looking like it will be the area where most of the metal work will be done.
I cut out part of the quarter panel section to give me access to the inner area of the door. Of course it is pretty much gone.
After I got the rotten quarter panel support out and the rotten rocker box reinforcement plate out this is what I had left to work with. I was warned by lks dcvn that the rocker box reinforcement plate was a bear to get out. Let me tell you he was not kidding!
In order to get the rocker box reinforcement plate off you have to open up the pillar area behind the door. For some reason GM designed it to where two of the bolts are completely hidden inside.
