Need 29-4 spring balance identified

Hello,

We can supply your replacement balances but it will need to be a custom order due to the length, extended travel pulley system and unique combination of end attachments. To confirm the correct replacement, we'd like to see a photo showing the side of the bottom fitting where the installation rivet attaches to the metal channel. We'll also need to confirm the number of balances that you need, with the minimum being two. Thank you!
