Where do I install this part. Plate, Grounding in p2015

I disassembled HP p2015 prinet there was physical damage on the side plates which I repaired but somehow I can not find the location of one small part that is Plate, grounding.Part number RC2-1568-000.

The service manual doesn't clearly show the part's locan. Can you please help me by showing this part's correct location.

 Thanks in advance.
