How much too small? Gms have a problem where the hole in the control arm gets stretched out and the new ball joint will fall out instead of having to be pressed in. Some aftermarket manufacturers make oversize ball joints to take care of that problem. If the new ball joint is just a little loose, you can tack-weld it in place. This is a rather common procedure. Just be sure to put the welds in a place where they can be cut off next time, and don't overheat the new joint.

The larger one was most likely already an oversize replacement. You're either going to have to replace the lower control arm or get another oversize one and weld it if necessary. If you prefer to replace the control arm, this is one time when new is a better choice than a used one from the salvage yard.
