Problem with replacement Idler Arm

Take a picture of what is in your car now.

Include the idler, centerlink and pitman arm.

Someome may have installed a 73-up large spline steering box that points the pitman stud downward. So they put on a 73-76 idler and just flipped the centerlink or put on the correct 73-76 centerlink.

Does the end of your centerlink look flat from the idler hole to the tie rod hole?

This is a 73-76 A-body centerlink.
