Some don't have bushes, all the others do but vary in length, angle etc. Trying to pull together and photo my examples but have at least 3 and looking on ebay there seems to be more. They all say part #C26116 part # too yet the parts range though Onan, Kolhler, etc. Anyone want to expand on the differences? As I said I will try to post some pics of my stash but I expect there are more?

Regarding EBay listings, I think people are not exactly accurate when they use C26166 in the description however they should interchange if the same length.

All Kohler engine clutches use the 6.5" fork whether 200 or 400 series, C26702 is the current part number. Early Onan powered tractors used the 5.5" fork (current part number C27031), later models use the C26702.

Regarding the many part numbers, earliest forks had no nylon bushing for the rod. They then went to the style with two flange bushings retained by a spring, nylon washer and cotter pin. The latest version has one nylon bushing and is retained by a cotter pin in the center. Other design changes have been made to strengthen the fork, angles and dimensions have never changed.

Part design has not changed without a new part number being assigned. Again, I think what you are noticing is people misidentifying the part that they are posting for sale although usually they will interchange anyway.
