Where can I get Lawnmower spares? (blade spacers)?

Question:Looking for blade spacers for the Lawnmower: Champion C390.

I've looked on various websites but cannot find a place which sells Champion spacers.

I don't think other spacers would work would they?

All help will be great. Website links, etc.

Thanks.
