Surly Single CogSURLY CASSETTE COG Our cassette type cogs are designed to fit on standard Shimano compatible freehub bodies. These cogs have a tall tooth profile that is essential for preventing chain skip from the extra torque a singlespeed drivetrain encounters. In addition to being a stellar SS cog, the cog base width (where it contacts the freehub body) is 4. 35mm, so you can stack a few of them up and use a 9 speed shifter for a simplified multi speed

Found one that fit.
It's a shame you have to buy an assortment just to find one that would work for my vehicle. You can't find an OEM one without buying the whole headlight assembly. Oh well.....
