Does anyone know who supplies the ball joints for the SLR/AC/Calmini control arms? The Calmini and SLR are obviously different parts. I have a torn boot and need a replacement. I looked through Moog's online catalog and found part number K9022 for a D21 upper ball joint. It looks like it would work assuming that Nissan hasn't changed the taper pin between the Hardbody and Xterra.
