so one of my PT hubs has a fair bit of slop, even though i just installed new bearings. i *think* i'm either missing a spacer or have the parts together slightly incorrectly, so i'm looking for confirmation of the spacers and sequence for reassembly.

it's the older 12mm alloy axle with thread-on ends (not the newer fat axle with push-on ends) to be used with campy cassettes.

i have the axle, the FH body, and a spacer that's ~1mm thick. when i pulled it apart the spacer was outboard of the FH body. i have a vague recollection that there's another really small/thin spacer that's supposed to go inboard of the FH body, too. can anyone verify for certain that's the case, and if so exactly where this other (missing in my case) spacer would go?
