no grease input on lower ball joint?

At the garage I work at we buy most all our parts from NAPA. I'm a little POed that this happens all the time. Order a pr of upper control arms for a Ford truck, one will have grease fitting one not. Hell when we order two of the same part number as in sway bar links, alot of the time they are two different manufactures. One may have blue poly bushings the other black rubber. You can't get quality anymore seems like.
