Window balance/ block and tackle

Home Owner from San Francisco
I need to buy a replacement of the window balance. Do you have this available? Also do I need a rivet installation tool to attach the plastic parts at each end?

Hello there. We can replace this balance, but it has to be custom made due to its unique spring strength. I just sent you an email with a custom link to order a pair. Let me know if you need a different amount. Note that the new balances come fully assembled out of the box with the top and bottom fittings attached, so no tool is needed.
