Can you provide an Internet link. Can't seem to find them in the usual online stores using Google search.
Maybe they have a special name.
Okay, that didn't take long, here is the link: https://jdparts.deere.com/partsmkt/document/english/featbene/DKD1607TractorLinkageGuide.pdf
Let me know if that is what you were looking for.
