I believe that black piece is a match for our 26-139 single hole aligner. You don't need to buy a new one since they can be reused. For the The 5/8" diameter balances, see our Series 600 spiral balances. I would recommend a red tip in each instance. Finally, for the 1-1/4" x 9/16" pivot shoe, I would recommend our 15-121. As for adjusting your spirals, it's actually fairly easy. You will need our 75-006 charging tool. See the media guide below for more information.

Hmm... if you have some balances that are Red tipped and some that are Black, I think your best course of action would be to weigh your sashes on a scale to confirm their exact weight. We have a chart on the S600-32 and S600-34 store pages that tells you how much each option can support. It could be the original installers just put in whatever was on hand, but if you weigh your sash you will know with 100% certainty what option would be best.
