It's honestly not that hard mate, just support the sump with a plank of wood between it and the jack,
then undo the cam cover and engine mount, then fit the new one and stick everything back on.
For the upper gearbox mount, support the gearbox in the same way, battery out,
undo the mount, mine wouldn't budge, but a bit of wiggling got it off,
then stick the new mount on.
You might need two people for the gearbox mount, as we had to silicon the nut to my finger
in order to get it into position under the battery tray, while my mate tried to screw the bolt into it.
The whole job is just nuts and bolts, it's not that hard, just set aside a good half day for it.
Oh and good luck finding a 16mm deep socket for the engine mount top nut,
took us 2 hours of running around shops to find one.
