So I've got a fix for the parking brake cable brackets. The larger bracket is not needed at all on 2019+ trucks. The listing says
"2014-2024", but the details inside the listing actually say "
The 2019+ trucks uses a rubber guide that functions fine with our added travel. The use of this bracket allows the cables to be less restricted, so we can add more suspension travel without kinking the E-Brake cable housing." So if you're not using the small bracket you don't need to do anything.
If you *want* to use the small bracket (I do so the cable doesn't hit my reservoir) they sent me updated instructions via text message that were a little confusing, but after reading them I used part of their instructions and came up with some better ones.
On the driver's side frame in front of the control arms unbolt the rubber mount for the right (currently upper) brake cable. This rubber mount can be cut off the cable, but I just flipped it upside down out of the way. It doesn't look like it's going to move or hit anything so I'm not worried about it. Unbolt the small bracket that's holding the left (currently lower) cable from the frame, move the right cable to below the nub the left cable was mounted to, then reattach the left cable mount to the spot you just removed it from. Basically you've just moved the right cable from above the left cable to below it.
Bend the clamp that's holding the right cable to the driver's side control arm open so you can pull the cable out of it. Slide the cable back a couple inches and then loosely re-clamp the bracket around it. I also wrapped a piece of split air hose around the cable for protection. See pics:

Now you can move the bracket holding the right cable to the top of the diff over. Remove it from the front left bolt and attach it to the front right bolt. You could bend or grind off the little mounting tab so it'll fit on top, but I didn't want to modify it so I just put it under the mount, adding washers under the mount at the other 3 bolts to keep the mount level. The mount bolts torque to 40 ft-lbs, btw.

Now there's enough slack to follow the Thuren provided directions for the small bracket on the passenger side.
I've cycled the suspension up and down like this and can't find any binding or rubbing.
