1974 Scamp some assembly required

Well good news I guess. The ball joint is fine. But on the other hand I'm a little concerned that what was loose and making the clunk clunk was the nut that wasn't even finger tight. WTH? Had a cotter pin in it to boot. At first I was thinking maybe the slop came from a worn-out ball joint, but the ball joint is nice and tight. IDK. Boot was shot so I cobbled one up I had.
