Idler arm too short?

Looks like you have a 68-72 K member or 73-76 k-member.

Looks like you have a 73-76 Abody center link. Although the B/E ones look the same until you measure the length.

Do you have a large spline power steering box (73-up) or small spline (72-down) ?

First guess is wrong idler or pitman arm.
