hey no trouble at all and yeah haynes is good for fiddly bits but tbh you have prob learnt more just cracking on ,
if you want put an axle stand or couple of bricks with wood in between under the engine , or tbh even when you undo the gearbox bell housing bolts it wont just fall off
the fiesta gearbox is relativly light compared to some so yeah two people could easily wiggle it off and on again, and if your doing the slave cylinder are you changing whole clutch, be worth doing whole job
