2019 Tundra with 4wc

I just upgraded from a 2006 tundra to a 2019 tundra. I have a 2012 Hawk 4wc that I’m putting on the new 2019 Tundra. My 2006 Tundra didn’t have bed rails and tonneau cover. But the 2019 does. I already took off the tonneau cover. So my question is:
Does anyone have a 4wc on their tundra, did you have to take off the rails/ track that the tonneau cover sits on? If not, will I fit?
I will take some measurements and it will answer my question but I’m asking because if someone has already ran into this, it makes my life easier. Thank u.

 

Because I had to look up Hawk 4wc to see wtf it was, and go measure my shit. I'd bet it will fit with the rails on.
BUT if it mounts like a toolbox the rails may need to be removed.
Thats pretty f'n cool tho.

 

My 19 / hawk I removed them. But can't comment if mandatory
