Just swap flywheel and install pilot bearing for trans input shaft.
CAVEAT; I have heard not all cranks are bored for a pilot bushing so it would be wise to inspect your donor before removing both engines.
Perhaps somebody here will be able to offer more

If you have both an auto and a 6 speed 540 it is straight forward. I did a 6 speed conversion on a 95 540ia. My daughter wrecked it this April. I am now moving the 6 speed drive train to a 93 530it shell.
