That's what I did, lift the front of the engine a bit first before inserting the wood, so you can get the input shaft aligned and gearbox bolted up before the engine is on the front engine mounts.
Many thanks to you both, my question has provided out with and in with the engine answers; whilst the g/box is resting on the wood support.
Works out well for me, as I will need to move the car around the workshop and that can be a faff when gearboxes are not removed with some other marques and models.
