roof rack cross bars
 

Have 2007 town and country lx model. Needed to purchase roof cross bars, received them in two styles. One is flat and the 2nd is bowed. Could someone tell me, who has oe racks on their similar vehicle, if there's are any different or are they the exact same.

They are both bowed. I've never seen flat ones before. Does the flat one fit?

Put a picture up, the rails and bars on my OEM set are [wind tunnel test] bowed, most aftermarket rails are flat, extendible and are designed to be clamped to (a) the fore to aft rack to replace the bow shaped ones and (b) mounted into the fore to aft channel vacated by the rack. Additionally Chrysler sell a set that are mounted 'on top' of the existing bowed rail.
