Replacing front upper and lower Ball Joints

I got the ball joints but the Bolts were not included. Can someone give me an idea of what to use for the replacement. I could use the old ones BUT I would rather start fresh and use new. I mean they have been in the car since 2001 so if I'm going to do the joints why not do the attaching hardware also. Thanks for any information. I don't know whay they weren't included so no need to ask 100 questions as to why. Maybe the guy who paced them that day was out sick.:runaround:
