does anyone know how much taller the xtra tall ball joints are compared to the just tall ball joints? what if i moved the mount back 7/8 and down a 1/4 and used the extra tall ball joint? im really just trying to keep away from having to notch and clearence stuff. still no opinions on whether the offset cross shaft is even needed? id buy the uca's and be done but as far as the money goes i cant really justify it if i can get similar performance for a fraction of the cost!
