Bedside supports

One of the things that bugs me the most on my Tacoma is the bedsides shudder or rattle when I shut doors.
Has anyone used At the Helm's bedside supports, does it help?

For reference the truck has bed braces, it did nothing to aid in the rigidity of the bedside (they aren't intended to).

 

I would love to but unfortunately IDK if the ATH ones would fit my WarFab Phantom HC rear which might be cut/positioned higher.
I've seen people make their own brackets.
I just took my stock ones, unbolted them, turned them up to act similar, and re-tightened.

Sounds are tricky to diagnose. First step when diag'ing a noise is to remove loose components in vehicle.
I've seen a pair of sunglasses in a glovebox or something, make it sound like a speaker grill from a different area was rattling.

Unfortunately with the build quality of this vehicle, and use it's subjected to
I was surprised to hear how much my dash rattles the one time I didn't have music on to hide it

 

Yeah its not an issue while driving.

You can just see the whole bedside wiggle around the wheel arch when you close the door.
