I know...I should've paid attention when I took it apart. It spins fine without, and it doesn't knock or anything, but my brain hurts. Anyway, If you can ID this and or provide any manual scans, it would be of great assistance.

NOTE: Square flats on the top race and locknut. Ball bearings on top, needle bearings on the bottom.
Thanks!
No luck after contacting FSA about this Duron headset. Since I've ridden without this mystery washer/seal, I've noticed that the headset doesn't spin freely. It isn't binding, but seems to sort of "stick". Anyone else familiar with this headset?
