Lost my battery hold down.

In "real" parts stores you used to be able to buy the J bolts separate. Dorman was one source. I don't have a good answer for ya. On my Ranger, I used a small scrap of angle iron, "straight across". I've also welded up a top angle frame all the way around.

The newer stuff is no better, LOL. You'd think since the Model T we'd have something better
