I used a small pin for a 1/4-20 collar from the super clamp to the gobo head to set the mount on top to mount C-stand. It was very unsafe so I looked for a larger option and it fit the bill. I screwed the Arca Swiss adapter plate onto it and then put it on a reinforced C-pillar. I have a Sony A6500 mounted on it and it seems very reliable as the length of the tube takes up most of the length of the gobo head.
