Bought a set of mudflaps for my T6.1, but ordered the wrong ones for the rear. These were quickly replaced by the correct ones which fit like a glove and easy, just two screws per side. The front ones are also easy but... I have read reviews that sat the ups provided for the holes underneath are too flimsy: here is my experience. On one side o fitted the plug with the screw provided and it came straight out when I checked if it was secure so I used the screw I had just taken from the inner wheel arch to fit the second bracket as it was fatter and it worked. When I came to the second side I tried the same but the plug split rendering it useless, so I modified a rawlplug with insulation tape ans araldite and it is now secure. Great mudflaps though. Thanks.
