Adarac truck rack question for 2014-2017

[SIERRA/T]

I bought an Adarac truck rack for my 07 LTZ crew cab.

I had it just in case I had to take my extension ladder somewhere or haul long lumber.

I sold that in 2016 and bought a 2015 Sierra crew cab.

The bed rails are different since they now come with factory bed rail caps/covers and have the handles incorporated into the rear pockets.

If I ever want to use it with this truck, I have to get new installation hardware (per Adarac) since the older style clamped directly underneath the pockets.

I cannot find any pictures or info how they attach to the newer bed rails or what the new hardware looks like.

My question is: Does anyone have one of these racks for the 2014-2017 trucks and if so, how does it attach to the bed rails?

Thanks

Bump.
