Anyone know the exact diameter of the side tubes on the roof rack? I don't have an Xterra, but am making an antenna mount for one for a 48" 2400Mhz omni. I plan to use a couple u-bolts to attach the bracket to one of the side rails, and I don't know the sixe u-bolt to buy. I don't have an Xterra to test on, otherwise I'd just go measure it (duh).

2"

Bought an ARB mounting bracket yesterday, it's 1.9" and just barely fits. Seemed like too much trouble to fuss with making one for me.

Thanks!
