Outer Limits 4x4 Board

Since getting my GU, I have noticed the similarities between the factory bullbars on the Navara and GU.

Are they interchangable? I'm guessing different mounts, but thought I'd ask.

Totally different shape, width, height.
Not interchangeable.

If your GU has air bags dont bother. Fitting a Navara bull bar will void your insurance.
