So, my hall sender disintegrated and I decided (foolishly?) that I'd do a
distributor rebuild.
 For the most part, all went well. No problem pressing out the pin,
disassembly was great.

Except.
 One of the black washers disintegrated. What can I use to replace it? It
would appear that without replacing the washer, the amount of up/down play
is too great.
 Any experience here would be appreciated.
 Thanks!
