Well I got it out thanks, once the bezel is removed it is just a matter of pushing it from behind and giving it a twist, and it is released from the dash panel. It is a nightmare trying to work from under neath though, I ended up removing the front seat and it is still an almost impossible task to see what you are doing.
New problem, how do I get the key barrel out of the old one, there is a little flat spring that needs to be held aside, I have the key in and in the central position and I still can not budge the key barrel.
