I am on my second Odyssey battery in less than a year, and while it has been good lately, I need to get rid of it for peace of mind. Talk of all the recent failures got me motivated to make the change before I got left hanging. Also, Funco says fucno to the Odyssey.
Problem is, the Interstate that I have used in the past is a tad bigger than the shiat battery, so it won't fit in the box that Funco fabs in their Gen 4 cars.
I made a tray that bolts in on top of the stock tray to hold an Interstate DCS-33, that way, no cutting and welding is needed. Here are some pics. I used 1.5" angle because that is all I had on hand, I think that 1" would work just fine and look better.
