I don't have my truck here today... but I think the ball joints bolt onto the UCA from the bottom and not through??? Wait a bit and someone with their truck or someone that remembers better than me will post.

These are replacement upper ball joints for use with CALMINI Upper Control Arms. Complete kit comes with an individual ball joint(1), spindle mount nut, bolts and lock washers for an easy install. Part mounts on the bottom side of our Upper Control Arm using the supplied hardware.
