Hi M3Boy
Can you confirm that you used the 2 original cap head bolts at the front i.e.. on the swing arm and then attached it to the body at the back.
So the front will move up and down with the suspension travel and the rear will just pivot about the attachment point.
I was looking to fix the whole thing to the swing arm similar to a motor cycle.
Indespension in Leeds have a good selection of mud guards to choose from so I'm going over on Saturday to sort one out.
