Did my install yesterday and did allot of research before I started. There are 2 ways to go about it IMO.
1 Using the right tools and not removing the motor mount.
2 Removing the motor mount then you have more space to work with.
I would suggest you use a lift and do it with the help of some one who knows how to lift the motor to get the mount out if you choose to go that route.
Took us 2hours with removing the mount to do the install
Have a look this attached file
