20" wheel spacers

[mantares]

I have two MP's that I need to install on my 20" wheels. I have been told by my wheel builder that it would be very difficult to spoke the wheels using the necessary very short spokes. Are the spacers shown on this forum available separately for sale? Otherwise I intend to make my own spacers, probably out of hard wood. Comments welcome...

I see that the Golden Motor 20" wheels have the MP integral with the wheel; the spacers are not replaceable or separate. If I had been a bit smarter I would have purchased two of those rather than trying to adapt my spoked wheels. Ah well...
