Thank you for all the help I used the rear suspension mount positions and some chocks under the front wheels and worked perfectly.
As people have said though you must use chocks under the front wheels, I went round a few time kicking them inwards so the they were tight as there is a tittle backwards movement when you are lifting the rear.
As for the reason that I had to lift the rear I will post that on my other post
