Singlespeed spacers, shimano cogs

[denmancentral]

Just looking to set up a singlespeed on a shimano hub, so I need a couple of the larger cassette spacers (already got some smaller ones).

If anyone has a 17/18/19 tooth shimano compatible cog, either from an old cassette or perhaps a single speed cog, I might also be interested.

Cheers

I'd avoid old cassette cogs apart from for testing ratios, they slip a bit
