The '50 and earlier trucks required 2 per door, but like Carl said, you'll only need one per door. When I did mine, I just ground the rivet flush with the arm and then punched the rivet out. The original rivets were solid and peened with a cold chisel in an X pattern, but for the ones from the Filling Station, you may need a tool for peening the semi-tubular rivet. Don't try to peen over a semi-tubular rivet without the tool.
