Those are tie-rod ends used for the centerlink...at least for the Calmini steering system.

I don't know if Mcquay Norris and Moog share the part number, but I just bought a couple of Mcquay Norris ES409R to replace the tie-rod ends for the centerlink... :rolleyes:

I also wanted find less expensive and beefier one for replacing the stock inner/outer TRE. I couldn't find one on time...
