So no one in the history of headsets ever made one that looked like two slammed into each other . I'm going to have a talk with my dad and beat him silly (I love the guy and it's the holidays but Jesus H.). The funny thing is if you knew my dad you would totally believe that he would do something like this. This is probably why he quit riding it in the first place! Let assume that we can tell anything from measuring the headsets themselves, and instead I need to measure the diameters of the headset tube, what numbers should I be looking for!
