Battery bracket, hold-down source

[Kacordy]

I have a 2018 Mini-Winnie. The dual battery tie-down bar is corroded and I need to replace it. Where can I buy that online? One battery has a ton of corrosion on it. It continues to grow even after spraying it red battery terminal spray. I want to replace both batteries and the mounting hardware and get a fresh start. Your favorite RV battery suggestions would be greatly appreciated also. Thanks for your help, Allen

We’re you ever able to locate one or did you have to build your own?
