I found this place in the Netherlands that claims to buyout NOS (new, old stock) japanese bike parts. They list the part but I haven't confirmed that they actually have it yet since it is the weekend. I'll post a follow-up.
i'll take seconds on the screen have been looking for 1 for about 3 months. have actually bought 4 of them all to be told they are discontinued and no where to be found but i keep trying and hoping i'll find 1.
