I agree, those rivets suck, I've found what works best for me was to grind about 2/3 of rivet head away, then drill center of rivet till just beyond the frame stack up thickness with 5/16" bit, then using a 1/4" punch & BFH, swing away. My air hammer (rivet gun) wouldn't budge em. It also helps to back up the frame next to the rivet but.
