I think the thinner one has been modified to fit a different case, its genuine but not the size it should be.
I’m hoping someone who knows more than me can help me confirm if these are genuine. I know there are more modern versions with etched numbers rather than stamped and I have somehow ended up with two different 633 end links and now have no use for them, I would be happy to move them but would like to be sure that they are genuine before doing so.
Any help would be greatly appreciated.
