King pins are new to me... I do remember my Dad mentioning them many years ago, but the cars I worked on didn't have them. I did the wheel rock test after jacking up the front and the driver side wheel was tight. The passenger side rocked about 1/8 inch top to bottom but I didn't see any movement on the kingpin or brake drum. It seems like a loose wheel bearing that needs to be snugged. The box looks older than dirt, maybe the previous owner was like me and hoarded parts for the future. I'm sure I will use them someday. Thanks for the replies.
