On the lift arms imagine a line from your new "eyes" to the ball mounting point on the tractor. This is your new lift arm. Lengthening your lift links to bring the new eyes/new arms to their original position will cause virtually identical characteristics to the original. Forces consolidated in the composite lift arm/QA will be different but not felt much by tractor hydraulics owing to the small change in angle. The sweet/ strong spot in your lift range will change a little. Loss of the outer ball articulation will cause some binding if you tilt implement. Moving your top link point will be the same as if the lower links are stock. --Lower link point reduces lift capacity some but kicks the implement tail up quickly as you raise.
