I'm in the exact same situation you are, but I haven't discovered yet that my riveter won't fit. One word of caution is that Rob told me to be careful of denting the door when the bit pushes through the rivet. He also said that it is hard to get the old rivet pieces out. I'm thinking I'm going to save that job for when I replace my T-panel. The metal under it is rusted pretty bad and I'm thinking about replacing it too. To do that I will need to remove the doors. One job leads to another! Walt Tampa, FL
