Roof Rack on Liberty
 

I just bought a '04 Liberty and was a little miffed that the roof rack
did not include cross bars. What good is it? I got the dealer to
order me a set of Mopar crossbars at no charge. I got them the other
day, and proceeded to install them. They look hideous, but they were
free. (Should be included, actually). Anyway, does anyone have a
clue what the locks on the end of the crossbars do? I cant see any
use for them whatsoever. The parts guy at the dealership is clueless.

Anyone?
