I am also in agreement with post #2. I believe that the .015 steel washer at the top is there as a thrust washer and helps prevent wear to the top of the casting tunnel. The fiber washer goes to the bottom. I am not sure the purpose, but most drawings show it there. When rebuilding a distributor I try to eliminate excessive thrust clearance. Sometimes I have to add a second .015 steel washer above the fiber washer at the bottom if there is excessive thrust. Other times I have had to grind material off the top of the collar at bottom to achieve proper thrust clearance with a steel washer at the top and a fiber washer at the bottom.
