Cycle roof carrier

fallingoff

I'm looking for a cycle roof carrier but am having difficulty locating one.
My car has roof bars running front to back rather than across the roof so adding cross-over bars will make the bikes sit very high.
I need something if possible to suit the std roof bars.
Searched Ebay,Halfords....thanks.

Thats how we have to do it, we have cross bars running between the built in ones on the roof, then longitudinal bike carriers. The bikes do sit a little high but nothing we can do about it. The bike carriers we bought were about £12 off ebay. There is a pic in the biking cars section of general mtb.
