No idea mate, i asked about setting one up, but was told i couldn't due to someone in the past messing it up.
My god what service, they have just phoned and are sending some centre clips they do.
The rears don't line up properly like in the picture above though. May have to ask for some clips to hold the two pieces together.
I'm so glad it just isn't me!
Ask them mate, they are very approachable.
