How to fix gimbal roll arm ring broken

[Angel]

Hi guys,

I broke this part of my camera (see picture attached) and bought a printed replacement on ebay.

How do you stick the "gimbal roll arm ring" to the motor?.
Do you use glue? (Now that is broken I cannot see remains of glue from the factory in it.... hmmmm
If you use glue, which glue would I have to use and how much?.

Any videos about how to do this?.

Thanks so much!!

This video here shows the shows the Yaw arm replacement in 12:30 but seems to be different than the roll arm ones

In this video they are not putting any glue in it and I think you have to glue it??. Not sure the kind of glue though....
