thanks for the pictures. is that a 67 idler arm? looks like has the stud mount. mine is shot on the end that the bolt goes thru it. looks like this one.
I don't know the year unless it is contained in the link I posted for you. As far as I know that is the only one that has been cut apart and posted on this site.
EDIT: Link said 1973. The picture only shows the knuckle end.
