It was a custom made roll bar. The rear bars follow the roof line all the way back down the back glass and the center bar in the hoop is removable with two bolts. Almost like having a swing out bar. So the swing outs are removable and so is the center bar and that’s where the room comes from. It’s good to 10.0 ET.
