Classic Performance Modular Drop Spindles CP30106-HD3

[Knight72]

Hey guys I ordered these spindles Classic Performance Modular Drop Spindles CP30106-HD3 from summit. After installing I found the dust shields aren't used, the calipers need an additional bracket and the 72 upper ball joints are loose in the spindle. Cpp says these are intended to be used with the 71-87 ball joints, but I was under the impression that they changed the upper ball joints in 73. Another site has the same part number as being intended to upgrade the 1/2 brakes to 3/4 ton, but that's not listed anywhere on the summit page. Anyone out there have a similar issue if you ordered these spindles? Are the upper ball joints from 73 up a larger diameter? I can push the top of the wheel in a good inch or two and the tires are leaning inward.
