I am looking to replace the window shoe for my United window (image above).
FYI, do I need to replace both sides, even if the other side isn't broken?
Thank you.

Hey there. This might be the 15-135 Pivot Shoe. Remove and compare to confirm. You don't necessarily need to replace both pivot shoes at the same time--but if one breaks, typically the other may not be far behind.
