Quite of rivets to pull. Since most of the holes are right up against the bracket, I had to use the hand puller along with a wedge. I always struggle with trying to keep from scratching up the surface when the mandrel breaks free, so I use a thick piece of card stock behind the rivet to protect the metal. Plus the wedge would go flying after each pull so I taped it to a paper towel to keep it in place. This technique worked pretty well.
