…After it was all back together the Haynes manual arrived and apparently we should have taken the engine out rather than just undoing the mounts and pushing it forward.
It's not uncommon for manuals to suggest doing things the long way round. For example, to get the Morris Minor master cylinder out (according to the Morris workshop manual), one was supposed to drop the whole offside suspension to get enough clearance to withdraw the master cylinder fixing bolts from the chassis rail.
We used to undo enough of it to get access to the torsion rod with a crowbar, then gently lever the torsion rod until the bolt could be removed. When re-assembling, the bolt was entered from the other end with the nut behind the torsion rod. Problem solved!
There's something similar on my current car, where one is supposed (according to the Haynes manual) to remove the steering wheel and half the dash to replace bulbs behind it. 'Tain't necessary!
