Right on. I'm curious about the rivets you're using, the tool for installation, and how bad it was under all the coatings/sealers. Got some photos of the job we could see? When I researched the job for my car most of the information I found was from folks who welded theirs in, so seeing how you go about it with the rivets would be interesting. Difficulty coming up with the right tool for the rivets was the main thing that led me to welding.

Did you examine the other side closely?
