Hello, It looks like you have either our S351-29, with a 15-002 bottom attachment, or S390-29, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need a 2840 spring strength option for your 28D stamped balances, 2850 to replace the 28E and 2860 to repalce the 28F balances. Comparison of the S351 and S390 balance shoes.
As fr your top sash guide, we've related a few similar options but you will need to carefully compare the dimensions on our product pages to determine if one of them is a match to yours. Unfortunately, we do not carry a suitable replacement for the second guide in your photos. Thank you! |
