Please see attached pictures of the part needed. Need both left and right, and also some plastic end pieces I think they are called shoes?

Hello,

Thanks for writing in! Your window balance is a match for either the S380-21 or the S385-21. To determine which of these is the best replacement match, carefully review and compare the dimensions below.

Our 2040 stamp option will support a sash weighing 15 to 23lbs.
