Yeah man, sorry about your shitluck but if they break you'll have to send them back, and Ill send you a new pair of OG's they have one slot in the back now so they sure wont crack, but we haven't had many problems with them cracking there at all.
No, it is just the tube part of it. just use the one that came with your headset. Im not going to include the star nut with it until we can also include the cap as well. Otherwise its kind of pointless to include it without the cap haha.
The version that comes with the bars is like this
All that comes with the OS bars is that tube spacer and the cap and star nut comes with the headset.
