Batboard

Hi -

I am looking for the back housing of the control head for a CDM1550 and the basic service manual I see a part number of 1586093B02. They then have part numbers for the"including" two ground clips and O-Ring (3986218B01 and 3286094B01). If you order the first part number do you get the o-ring and clips with it (I'm thinking no...)? And if not does anyone have recent part numbers for the clips and O-ring?

Thanks for any info on this....
