I need the z shaped or double L shaped piece that goes on the back of the lock tumbler. The parts manual does not give a part number for it. The manual only shows a lock assembly. I assume the same piece for the B is the same although the part numbers are different for the lock assemblies.

Any ideas about where to find one of these parts?

It's standard cabinet lock hardware. Any lock shop should have the cams, but you might have to buy the whole lock that goes with it for around 8 bucks...
