Coil balance replacement

I am fixing a customers window. It has triple coil balances. I already ordered the carrier setup, and I can't figure out how to get all three coils attached to the bracket. After research I came across the same question answered on your site. I have given up on using the original setup, and I am going to order the S140 series. My question is, do I need to purchase anything else aside from the pivot bars (originals are the "c" shape) to install these? Do they use the same bracket that the original coils were attached to, or is there another bracket?

Thanks for your help, looking forward to a response.

Thanks for the information. I ordered the S140s, and pivot bars yesterday. Just wasn't sure if there was another accessory I was missing. I will reply again after job is done, to let you know how this went.
