Are you saying that the ball joint taper bolt was spinning in the ball joint? Bolt the ball joint back in place on the A-arm with proper sized grade 8 bolts, then seat the taper into your spindle by placing a large socket over the bottom side (protect your zirk or the threaded hole for the zirk) and rap it up sharply with a hammer. Shouldn't take much to set the taper in the spindle, then once your nut gets past the rough spot you'll be fine. Sorry if I am misunderstanding your problem here.
