I get it now, that makes a lot more senseWell I'm not having any luck finding what I'm looking for. Basically there was a metal bracket that bolted to the inner fender. Then you had the actual hold down that would mount to that. The hold down was shaped at an angle, which allowed it to go straight across the battery even though the metal bracket wasn't right in the middle of the battery, as you can see looking at yours or mine in my pic.
Here's what LMC shows. The metal bracket is number 2, but they don't show it in the proper shape.
And here's a pic of the hold down. You can see the angle I'm talking about.
