We are attempting to replace the balances of 2 windows. They are marked C 28 BSI. We also need to replace the top sash guides, but cannot identify it. We believe the channel balance is a 2830. Here are pics of the balance and the sash guide that we are attempting to replace. Please let me know what other info helps. Thank you.
