Frame rail transport tie-down hooks

Hi,
The 2017 owner's manual shows the correct frame slots to use when transporting the truck on a flatbed transport truck:




However, no guidance is provided regarding the correct hook to use, and there are several different styles:



There's gotta be some way to figure out which one is best to use, just can't seem to find any reference.

Thanks,

David

 

Ummmm any hook that will fit will work. Looks like the longest in the pic will work.

 

I tried two at NAPA today, and both sorta-kinda got in there and held, but neither really convinced me that they were the right one.

Also, I'm known for over-thinking this kind of thing
