Has anyone used t-hooks of this type in the factory transport tie down slots in the frame rails (the ones that have rubber plugs on delivery...I'm guessing they are for transport tie down)?

I'm not sure if they'll fit and would like to know before ordering.
Thanks.

they're all the same as far as I know

 

Yep, most all of the t-hooks are the same dimension, but they also make a bunch of other type hooks for different applications. What I'm trying to determine is if anyone has used the common t-hook with our cars, in the factory tie down locations. I know Jason said it was an option, but hadn't tried it. I'm just not sure the the "T" part will fit into the slot...
