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

One day of PTO + one all-nighter + both weekend days, and.....

Working on Bazza's '71 VG Valiant (RH drive, Aussie car), and because I busted my *** all weekend, I'm almost to the point now where the car is in the same condition as when I picked it up- i.e., in about 100 pieces. A good analogy would be that I'm trying to assemble a very small jigsaw puzzle....but without the picture.

Having said that, can someone please tell me, what is the bar/strap?

For reference, this is the LH side of the car, and the lower end of the this bar/strap is bolted to the k-member (I never unbolted it). I assume this doesn't bend over somehow and get bolted to the engine as, 1) the hole doesn't line-up with anything, and 2) it would render the engine mount almost moot.

Is this some sort of grounding point for the battery/ignition? The battery box is "right there", and this is all I can think of....

I'm just hoping it isn't an Aussie-only thing, as Bazza has no pictures of it.

Thanks, everyone.

Tired as hell,
Jim
