Thanks for reaching out! Yes, I do agree. The balance you have here is the S770-29 with a 29B Stamp. I believe the plastic piece you are describing is the 26-200 Balance Screw Plug. Although, it would help to see the part installed to confirm that this is the part you need. Are you able to provide a photo of an undamaged piece, installed in the window frame? Alternate image for 26-200
