Replacement XX-4 one way pulley

[pugboy]

I bought a used xx-4 which came with a front 1-way (blue alloy) but the pulley is a bit worn from where I snapped a belt. Anyway, I know it's not a Losi part and reading round people say the 1-ways were made by DC racing or Lesro (?) or Apex. I've tried looking and can't find anyone listing spare pullies, or even the 1-way at all.

Does anybody know where I may be able to source a replacement pulley, it's only the plastic part I need?

Any help most appreciated.
