Thanks for reaching out! Your channel balance appears to be either the S380-29 with a 1" shoe depth or the S385-29 with a 1-3/32" shoe depth. To determine which series you need, you'll need to confirm the measurement for the depth of your bottom shoe.

Since your balance is stamped with a 28G and the sash weighs 39lbs, I would suggest using the 2865 stamp option.

Comparison of the S380 and S385 balance shoes.

I'm sorry to say we do not sell a replacement for the plastic piece you have pictured here.
