Misc. Does anyone know what this connection set up is for on the front bumper of my CJ5?

Does anyone know what this connection set up is for on the front bumper of my CJ5 ? To use for towing would be my guess, but no idea of the set up. Also, I want to connect a shackle. One seems to thin and would be too much play on the shackle. Shackle won't fit between or outside both horizontal plates. Wondering how best to make in to a shackle connection point.

A little hard to see, but looks like it is set up for flat towing

Definitely looks like it's for a custom flat tow bar.

Like previous posts.
Looks like Flat Towing Brackets for a Horrible Freight Adjustable Flat Tow Hitch. I think they still sell them.
I have one and it worked well.
I flat towed a Samurai to Elko, Nevada and back no real problems.

Just remember!!
The Flat Towed vehicle
HAS NO BRAKES.
Which made a Very Interesting Trip Back through the Mountains in a Pop Up Snow Storm! Finally getting into Cheyenne at 15 mph or less for 3+ hours ... laid over to Settle My Nerves and extract the Seat Cushion from my <-BAD WORD-> !!
