Same old Mondeo bonnet catch problem

[Marshon]

Hi guys, can someone throw me a bone here. Following a rather harrowing accident an object hit the front of my bonnet, the catch popped and the wind threw the bonnet back over and into the windscreen. Now the car's been a great runner, but it's worth less than a grand so the £400 excess to have it repaired wasn't economically viable. I've managed to get a replacement bonnet, new hinges and new support rams - all fitted without problems, but the latch mechanism is damaged and unserviceable. However the lock mechanism still works perfectly, so I've bought a new latch, my question is, how do you get the old latch mechanism out? Is it possible to undo the two retaining bolts and either lift out or drop out the old one without having to start butchering the lock?

If anyone has changed out this unit and can give me some pointers that would be great. All the searches I've done turn up loads of things about bonnets stuck closed or unable to latch correctly but very little about actually replacing the latch, not the lock.
