Jamis Parker pivot bushings & such???

Can we assume that you've already contacted Jamis?

I know where to find an 09 Jamis Parker for sale...

This?

I don't get it. What do you mean by "This?". Was that a typo?

No, no typo. I was more reiterating your original post. By saying "This?' I was more or less asking the same question that you originally asked.

@ Phluff. Ah, yes yes, just so. Back to the original topic. If you can't get them from Jamis anymore, which would be pretty lame for a bike company, you can find almost anything at McMaster Carr. It's an industrial supply company. Remove the old parts and CAREFULLY measure all of the dimensions, as in with calipers, down to the thousandth on an inch, or millimeter. Then go to McMaster Carr and go through the lists until you've found the exact bits of the right material and dimensions. All the options they offer can get a bit confusing. But eventually you'll get there. The bearings, by the way, have a little code on the plastic seals that designates the dimensions.
