The broken release assembly is a LEFT hand side in black. The locking tongue is broken off during installation and the installer is long (3 years)since gone.
The photos depict a right hand sample which was easer to photo than the actual left hand broken assembly.
Please don't refer me to repair company. It would only take me 1 minute to replace the part myself.
Thanks...
