you can wiggle to your hearts content on my landy.....
there isnt a gap big enough for the starters smallest dimension - up top or down below.
you have to drop the exhaust and the turbo feed/return pipes to get it out.
Clutch is just floor plates/seat box/tranny tunnel out.
Drop props , remove the slave cylinder
undo engine mounts to allow engine to rock , remove gear box mounts and undo bellhousing bolts - slide it back.
Admittedly if your landys 20 years old and half that stuff never been out it will take forever....
