Is there a little mud flap or something you can get to put on where the holes are as the wing sticks out about an inch too? http://www.dvcvh.co.uk/DVCVH/Shogun.html#8 Here is a link to my site images so you can see what I'm talking about.
Indeed i can all i did was fill the hols with rubber grommets from Halfords then if your not bothered with the side steps i cut out the rear plastic bit of the step this makes a good front mud flap and then i cut a bit from the front pop rivet it to some rubber car mats to give a bit of support and that makes good rear flaps hope this helps.
