Basically you want the most expensive one for $899. That is the full blown EXP auto clutch and comes with everything to be an auto clutch and a new Rekluse clutch cover. Why anone would want to do the other options is beyond me. Maybe MX guys who want to convert back and forth?

This is the EXP auto mechanism you add to the core manual clutch assy. listed above to make it the full blown EXP auto clutch.
