Parking brake

[Ridgeline]

I picked up a 8.5 rear end out of GN. It had some parts missing and I need the assembly that works the emergency/parking brake on the rear hub assembly. Don't have a clue as to what it looks like or even other 7.5 parts will fit. Anybody got any help?
Thanks

The 7.5 parts will fit, they both use the same backing plate.
