Hello, Has anyone found a replacement (or know the Keysight part number) for the spring metal clip that provides a ground to the front panel of the 3458A? It is a small <1 inch clip, bent in the center and screwed into the chassis. When the front panel is snapped into place the clip contacts a big pad on the PCB and provides a ground. I have a 3458A in the works and it is missing that clip. I have called Keysight before and they were never able to provide the correct part. Thanks, Victor
