Broken pulley system

Hello there. Can you tell us the length of the metal channel, not including the nylon attachments at both ends? Can you show us any stamp on the metal channel? Finally, can you show me a closer picture of the bottom nylon attachment? We'll do our best to help thereafter.

Thanks for getting back to me. You have either an S351-25 or S390-25, depending on the depth of the bottom nylon shoe. See below. Measure your old balance's shoe depth to see what matches best. For a stamp option choose 2420.
