I don't know the specs on the rro bars, but mine come with precisely measured round holes instead of slots.
The specs on mine are:
1.32" x 0.133" structural A500 tubing with 1/4" thick feet.
The rise is about 3.75" to the top, 2.43" to the bottom. The actual distance between the roof and they side rails is variable because the roof is curved, but its about 2" in the middle.
For the racks, the crossbars sit nice and low, about 3/4" off the roof at the lowest point.
There is about 45" if flat in the bars. When installed there is about a 48" space between the bars, 46" in the rear. The roof actually tapers in toward the rear, thats why its narrower in the back.
