Hey all just a heads up. The revolver X2 will not fit with the reg. 6'6" box. Made this mistake. Got everything cut and the bars installed but the tonneau scrapes the sport bar and has to be jammed in while rolling. This is because the 6'6" box tonneau has a thicker roll when passing the sport bar. Will try some more tricks tomorrow, hopefully will be able to grind the track of the tonneau cover down to make it fit. Only need about 1/4". If anyone has any ideas please share!
