You have come to the right place. I am going to list a variety of different parts I would like for you to take a look at to see if any of these would work as replacements for you.
Let's begin with recommending our
26-228 and
26-229 tilt latches. Moving on to your pivot shoe. For that, I am suggesting our
15-046 as being a close match. Next, see if our
26-040 pivot bar would make a good alternate for your current one. As for your spiral balance, our
Series 600 would make a good choice. You would need to know the metal length measurement as well as the color of the nylon bearing at the end of the tube to determine which balance to use as a replacement. A good helpful tool to always have when adjusting these balances is our
75-006 charging tools.
