Question about Prinsu top rac

I just picked up my Prinsu top rac in the mail but I still have not received my LEER 100xr Canopy. Am I going to need to purchase any additional hardware?

 

As long as you got the factory rails installed, you should be fine, I didn't have to get any additional hardware. A side note, my Prinsu hardware was T-27 bit. Not a T-25 or T-30. I've been in the trades for almost 30 years, never knew there was such a thing. Stripped a bunch of my heads out.

 

Can someone with a Prinsu top rack measure the distance from the top of the camper top to the top of the Prinsu rack (highest point, whether it's side plates or rails)? I've attached a pic as an example. I'd like to get a Prinsu, but only have a couple inches to spare when pulling into the garage.
