Hello,

There's a good chance that we can help but the bottom fitting of your balance where the pulley extends from is a bit wider than we normally see. If you could show us a few more photos of the bottom fitting from additional angles, as well as write out the exact depth of the shoe, that would help us narrow down your options. Please also include a photo of the metal clip at the end of the pulley cord. Thank you!

The S350-27 (2650) is similar to the assembly shown in your photos but I can't be sure if it is an exact match without the additional information we requested. You're welcome to give them a try and if you notice any discrepancies, feel free to get back to us and we can go from there.
