I'm trying to source some parts for a stand. They are the darker metal parts in this picture; th roller adjuster and mounting pin that goes into the handle. I have the threaded section. Anyone know where i might find these, or anyone have some, or even a prs-3 clamp arm? Any help/info would be muchly appreciated.

Have you contacted their UK distributors?

If you have no joy with Madison just email Park, I needed some parts for my PRS11, Madison did not reply to me and Parks sent me the parts FOC.
