Hi there!
We can help but I'd like to see close up pictures of your top fitting from a few different angles. That will help me determine what kind of balance you'll need.
Your metal channel should also measure as 13" so we suggest triple checking that measurement to confirm.
Thanks for confirming! These pictures appear to be the same ones in your initial batch of pictures, however. We'll need to see up close pictures of your top fitting from a few angles in order to determine a match.
Thank you! This looks like a good match for our S377-13 with the 1220 spring strength option. Look over our specifications and see what you think.
