Looks like your sorted now Coops.
Sorry I didn't respond, didn't see this as I have not been on much.
With regards the bonnet plate, I have asked a member of the Constabulary about the plate and have been assured that it is fine.
It's the same as normal plates, as long as you stick to the font and font size specified. The site you buy them from will however state that they are not road legal, but thats probably to stop any aggro on their part.
Craigs Plates is the place to go.
