Ok i looked at the parts Fiche and it lists the original Part numbers as
43432-KA3-730 Collars (need 2 of them)
91272-KA3-711 Dust seals (need 2 of them)
these numbers may be superseded by others
the Spherical bearing is not shown as a separate time, but if my cloudy memory is right i think it is a standard "IKO" brand and can be sourced from a bearing supplier if you pop the original out and measure it up and take as a sample.
as Brad said EBAY USA is you best friend here for CR500 stuff, nothing available 2nd hand here pretty much.
and welcome to the Red side
