End link attach clips on pre 73 lower arms are way out toward lower ball joint. 73 and later have the clip closer to middle of lower arms length. I honestly can't define by that picture.
Most aftermarket add on bars came with a right angle piece to add at lower shock bolt so end user didn't need lower arms with factory clips. Todays aftermarket offers oversized, hollow, etc., that attach same as OEM. In that case you must know what year/type lower arm you have.
