I already explained in the chatbox but... if your riding a stock old a/b/pro, take a bolt and put it behind the neck on the folding mech and tighten it up... the neck will stop moving, if thats not enough proof than i don't know whats wrong with your dad. Now reason for putting 3 of your own bolts in is because you can take all of the folding mech guts out of the neck that make noise when you ride, and so you can have nice strong grade 8 bolts in place of the stock razor china bolts that could break while your doing tricks.
