Got that right dankar04, as inexpensive as servo arms are, they could throw a few more in the bag. I have had some that the hole for the screw used to attach the ball to the arm, was to small. Had to run a smaller screw with a pointed tip as a tap to open it up. One mistake, and you need another arm.

I use #11 Xato blade to gently open up start of hole for ball. then thread screw on with out ball link. Once threads grip remove and add ball. Those screws be thin but do go in. FWIW Futaba S3114's sevos fit and come with extra arms. Easier to get and rebuildable.. They are smoother than WK servos also.
