removing top of a bosch pump

[Jimbo]

So basically I have got a gov assembly springs etc. I have put a nut in the main spring for the gov mod. Im just not overly confident on removing the top of the pump (still on car). Although im a mechanic by trade its not something ive done before. Ive read the guide over and over and I understand how to do it its just that I dont want to break the cradle it sits in. Id rather someone helped me .

Just wondering if someone could write basic guide and any specific things to look out for. On the other hand if someone wants to give me a hand id be happy to pay or whatever

Cheers
