I searched all over trying to find someone who did this. I don’t like the looks of battery’s in the engine compartment. Anyways I am going to throw my design out there. It’s not finished but it’s all down hill from here and if you can make this part you can build a hold down and paint it. Hope this helps anyone else in the future that wants to move there battery out from under the hood. It still needs to be wired but I’m not posting all that unless there is a huge response on this wanting more info.
