I reached out to Yakima and was informed that there unfortunately is not a compatible landing pad for Q-Towers available so the only way to mount your Yakima crossbars would be to also get new towers. You would also need some tracks to mount on the roof of your A.R.E. Truck Topper to have something for the towers to mount to. We have the following track sizes available:
42" # Y01126
54" # Y01127
60" # Y01135
Since you have Q-Towers I'm assuming you have round bars and would need four... view full answer...
