Replacement for spiral balancer attachment to sill

Question

Hello, I am trying to source a replacement part for my window. The attachment to the spiral balancer is broken (plastic) on the right hand side. The attachment showing the left side balancer is attached to the sill with a metal piece inserted into the bushing in the plastic housing. The reason the right side piece is broken is because the builder installed trim nails into the channel for the sill to translate. Subsequently the plastic piece interfered with the nails and eventually broke. Please let me know if I should just replace both sides with a total assembly.

Hello, thank you for writing in. Could you show me an undamaged version of the pivot shoe, removed from the window? I will also need to know its width and depth. All of this will help me identify the best replacement part. Many thanks!
