My 74 Duster Project
After finding the poorly patched floor pans I remove all the bondo. In retrospect, I wish I had replaced the entire floor pan. However, at the time I decided to just patch the holes. I also found similar holes in the trunk floor, so I did that as well. I also cut out the spare tire well and "cupped" the new one in. I don't think I did a bad job on one of my first welding jobs. Not perfect by any means, but....
I did find a couple pictures on my computer, but I am having a brain fart as to how to post them.
