Hi fellas...I have a 92 Laredo with the factory roof rack. I need to take the cross bars off the rack, but not sure how on this one. On my other 92, the roof rack rails are "flat" and you simply screw the rack off the base, just as you would loosen the cross bars to move them. On this 92, you have a push button that allow you to move the cross bars, and the rail is more of a "triangular" shape than flat. Surely someone out there has one like this? Thanks up front.
