I'm wondering if anyone has added additional tie downs to the floor using the T slot. It looks like it's just standard 3/8". Trailex sells these

but I'm looking to add tie downs that fold over when not in use. I also don't think i can slide in T slot nuts since the ends of the rail are finished/covered.
