Broken Coil Balanace

I need to replace a few of the coil balance mechanisms on some vinyl single hung windows. I have attached photos. the copper color metal coil has broken off a few. I suspect that I need the coil, the saddle, the seat, etc. Just need some help with confirmation of what part numbers based on the two photos provided. One is the right side coil and the other is left side set or saddle?
