Is this radiator overflow bottle bracket factory stock?

This 4-door ‘68 Coronet 500 has this bracket that I believe held an overflow container. The radiator support has factory holes for it. It is an air conditioned car. I’m just puzzled.

Looks like the same aftermarket overflow I put on my Jeep years ago. I've never seen a 68 with an overflow that wasn't added.

I didn’t think any came with an overflow but being an a/c car had me wondering.
Thanks!

Tack on a few more bars, and you got a miniature shark cage !

Aftermarket. I use a similar setup on a 69 r/t with a 22" radiator.

That's aftermarket. I just bought the same one

Since my battery is in the trunk it fits perfectly in the empty space

Yup, aftermarket. PO of my daughter's 69 Charger RT has a similar cage overflow rig. Daughter wanted to keep the overflow capacity so I used an older Mitsubishi Mirage overflow container, right next to the radiator. Had to fab a bracket. Almost looks stock.
