Please let me know what is the correct part to order considering the above pictures of the plastic things attached at the end of the part. Some are marked 27 4 AP and some are marked "27 3 BP"

Hello,

With this combination of attachments, you could have either an S380 or S385 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. You'll also need 2730 or 2740 strength options to replace your balance with correlated stamp codes. 

Thank you and let us know if you have any other questions or concerns.
