Camera / Gimbal Mount Case

[Brad Neill]

I have a problem identifying part of the Camera / Gimbal Mount Case

As shown the base plate or lower case is broken where the gimbal attaches. What I need to know is what this piece is called so I can buy one. Hope some one can help me out

'Gimbal - bearing retainer plate' maybe.
