I need to replace 6 of these balencers. Cany you identify via the photos and provide part numbers so I can order them?

This looks like either our S380-30 or S385-30, depending on the depth of the bottom nylon shoe, or the 'heel-to-toe' measurement. Compare both with your old hardware to see what matches best. You'll need a stamp option of 2950.
