Hey there, thanks for posting! Your pivot shoe appears to be the 15-180 coil balance shoe. Look over the dimensions for the shoe below and compare them to your existing shoe. See if these are the right fit for your window.

These are compatible with the Series 190 Coil Balance Spring. Since yours is stamped with an 8, you'll need the S190-840.

Your support clip appears to be our coil balance clip, part 15-186. You may also need the bushing coil 15-182 and a few screws 33-073.
