Guys thanks for all the replies, very helpful.
Think someone had a problem with the captive nuts in the past as they have cut a square hole out the front of it for access,
luckily this is covered by the number plate though.
Its a discovery 1 ive got though so looks like I will sell it on.
Oh well we live and learn as they say
