The little plastic top strap holder broke

Ah no. Same thing happened to me,not that long after getting it. Forget about finding the bar as even superglue won't hold it. I did a short term Jerry Rig by placing the strap between the headset and the visor, but it's short term. So,, what you need is a halo style strap where the attachment bar isn't needed. I got one and in a way I was glad as it's much more comfortable! Make sure it is one that anchors to the side. In the first photo is the halo strap I got and the bottom photo just trying to show how I placed the strap behind the faceplate. The one in the middle is accidental! Lol. Sorry, the lighting isn't good on the first one, I just took it now and my lights are low but you can get the idea.
