Here ya go. I can see evidence of a screw at one time being threaded into it. I don't think I was using it as all my pre-teardown photos don't show a ground wire on the negative battery cable. (Replacement cables, of course.)

The only problem is that the battery needs to placed with the negative terminal next to the radiator so the ground wire will reach. Most examples and documentation I have seen show it that way too.

I wanted to place the battery with the negative on the fender side so the cables would lay nice off the battery instead of them angled out. They can't go straight back as they won't clear the Delco caps on the Battery Topper.
