What is this strap/bar on Aussie K-member?

This time I set up a light to get some better pictures and now see that it was not a tab but rather just a hole on the side of the mount.
Thank you. It looks like your battery ground is attached at the same point where the strap/bar is on this VG, so maybe....

Either way, that's a really nice looking car, and I would bet you get a lot of questions and/or attention with it!
