Long time visitor to the HAMB, recent member. I'm building a Model A pickup. I found an original box that needed some TLC, rust in the typical areas. I disassembled it to make those repairs and decided to shorten it in the process. The pieces are ready to go back together and I would like to use rivets to match what Ford used. What's the best source for these rivets? How do you get the round head on both sides? I've done riveting with a pneumatic rivet gun and the "shop head" comes out flat instead of round. Any help would be appreciated.
