I need a couple of 2 mm thick spacers for a 9mm front axle--the wheel was apparently set up for a 96 OLD hub, and I'm using it with a 100 mm spaced fork. Where would I find such a thing? Spacers for 10 mm rear hubs are as common as sin, but I'm not finding any 9 mm ones. Loose Screws does list one 9 mm hub spacer, but they're 1.2 mm thick. Also, they're described as Campagnolo spacers, which bitter experience suggests to me means that they're cunningly designed not to work in with anything that's NOT made by Campagnolo.
Anyone have any suggestions?

Use 2 or 3
3/8" washers on each side.
3/8"= .375"
9mm = .354

Should be easy enough to find just don't get hung up on Campy or even bicycle when looking 2mm thick and 9mm inner high grade spacers you just need the outer measure for campy which was none standard but most any size smaller siz will work if the inner is right. I could find these in most ACE hardware stores for under $3 a SAE grade spacer washer is basicaly the same and will work if it fits.

I always try to find and grab old discarded front wheels for parts. Any old Atom front hub for example, will have at least two of the needed 2mm washers. If was a 100mm hub, there will be two on each side!
Most common Shimano or Joytech front Q-R hubs will have one 1mm washer per side.

I keep a huge, organized assortment of rear hub bits on hand for rebuilding and/or re-spacing rear hubs.
My Q-R front hub stock is limited to just a few hubs and axles, plus one baggy of misc spares.
I have a separate baggy for the 8mm solid axle bits, believe it or not organized between metric and what I think are 26tpi threadings.

Many of those hardware-store 3/8" washers will clear a 10mm axle.
A 5/16" washer might easily ream or file out to 9mm, and these usually have a more-appropriate OD for hubs.
