I would give Performance Fishing Products first chance being local to you and the customer service side of things.
If that does not work Russell Marine has used LVS 32 units posted for $850.
FB market place will have used as well but they seem to be running the same price.
My advice.....if you're planning on getting pretty in depth and commited I would save and "buy once, cry once"!
You have a nice rig that is capable and will serve you well but you will invest more in addons than what it is worth....is that a bad thing, absolutely not!!
Ask to go with friends with different equipment and test it for yourself to see what fits you the best.
Sounds like Ruger has a 9" LS setup, I have your same boat with 10" birds and 12" LS.
Blueball has us all beat with the 8616 cats meow!!
Your welcome to come with or check mine out whenever I am down, it stays at Brittonford Campground.
