Trust me Paul I did try moving it back but it doesn't change anything, the parts are out at the top and the bottom, the bracket doesn't fit into the largest centre piece of plastic so that is also an issue. Believe me I wanted this to work, slight gaps ect I can deal with but this is simply a mess, I feel for you as I'm sure it's a disappointment but I feel your frustration.
I'm going to have to remove it as it doesn't look pretty at all.
I will send you my bank details for the refund, I paid £35 to you for the plastic as
@A2Steve gifted me his bracket and that works just fine.
Regards, Mark.
