Email S&S Archery about it. They helped me pick out the right one for my Fast Eddie XL that uses the rod like yours. I think it's an older model. I know you said above that it might not work, but I think it's worth reaching out to S&S about it if you haven't already.
It showed up today, but I'm on vacation and haven't been able to check if it worked.
For reference, I'm putting it on my V3X 29.
