If you check out my gallery you will see some pics of my new brake booster/master as well as pics of the replaced floor boards. Not before/after , as such.
Yes the issues are pretty much the same, but I think I had less rust overall- my truck came from New Mexico. Also my truck had the current paint job when I bought it. Not a great paint job, mind you, and there's quite a bit of bondo on the bed sides.
Let me know if you have specific questions. Feel free to start new threads with each subject.
