Bonnet Mounted Spare Lock Post

I have a Series 3 SWB with a deluxe bonnet. I am trying to remove the lock post for the spare as I have moved the spare to the rear. I can see two bolts which I can loosen to an extent but cannot remove further is there a way to remove these or do I have to take off the complete mount, which I want to keep on.
Thanks
John
