Follow up: I remembered I had all the old Emergency Brake stuff from when I bought the car. I had ordered all new everything. In looking at the parts I seem to see the old style (See Tom's picture #14) arched link is just slightly different than the new style (see my picture #5). The old one just strikes me as flatter and less likely to push the pin out toward the drum. I marked all the pins with chalk and I used the old part and reassembled the thing with NO axle shim. I ran the car for about 10 minutes and disassembled. No indication of rubbing. Reassembled. I'll check in 300 miles of real driving.
