Specific Spacers

[Kezzieboy]

Was gonna chuck this in my other thread, but it's a bit of a different request.

What I'm looking for are 15/20/25mm spacers, but the stipulation is that the outer spigot, that the wheel sits on must have an internal diameter less than 57mm.

Aside from that, they just need to be 4x108. Bolt on or bolt through are fine, preferably with associated bolts, but that's not crucial.

Cheers!
