if you look at my pics Tezzer has cut off the higher brackets.. but yes the bottom 4 are enough.

I am not a mechanical engineer but having worked in industry where using bolts that are mis-aligned, you are not going to get the strength from this arrangement. Tightening the bolts to the recommended torque will in fact bend the bolt and the pre welded nut to such an extent that premature failure will result. I have seen bolts that after pre-stressing, a crack appears in the thread and corrosion takes over in a very short time, leading to failure.
Solution 1 Will slotting the holes in the bull bar give enough clearance. Then use oversized washers between the bull bar and bolt to spread the load.
Solution 2 I have seen tapered washers for this type of application so keeping the bolt at right angles to the nut and the torque is taken by the whole surface of the bolt head, instead of the edge of the bolt.
You will need a pair of these washers (at the correct angle) for each bolt.
1 each side of the bull bar. These washers are used when clamping items to RSJ's as the edges are tapered.
Am I being too cautious....:nenau Just look at the bolt head, ready to shear off..
Worth thinking about. Just found these hemisperical washers. http://www.firstfixdirect.com/scp/Washers/Hemispherical_washer_and_cup.html not sure if they would do the job though...

thanks for that Rustic. im sure al lwill be well. IF it wasn't just for SHOW then yes id agree it needs a wedge washer, but as its only ever goting ohave two lights on it i cant see that its much of a problem.

I agree Zippy, but I didn't want people using this method for more critical alignment issues, when things don't fit. "Wedge washers" so that's what they are called, I told you I wasn't a mechanical engineer..
