Front roof rack

Does any one know what is involved in removing the front roof rack assembly?

Seem like most duties could be handled by the rear cross bars alone.

Also will the cross bar on the front fit the rear bracket that has no cross bar?

This may be a stupid question because I haven't even looked up there except from the ground. New car.

Waiting for wheels and Borla system to come in.

Any one done this?

Thanks,
Allen
