Specifics...
I don't know the specific mfgr of the originals, but you should be able to come up with a pretty good match using a generic gudgeon design. If yours is like mine, the bushing material wears out in time and won't hold the pin/rod firmly enough. I cleaned out the residue of the old material in the opening and re-bushed it with epoxy plastic weld. It has worked well for several years now, though showing a little wear at this point.
