Jacking up the car is a bit tedious but not a problem, but the tricky bits are lowering the gearbox onto my chest, I once dropped it onto my face, and offering up the gearbox after replacing the clutch. The only time that the latter was easy was when I aligned the splines using an old input shaft, the other thing that I did on a Sierra clutch was to file a tiny chamfer on the back end of the clutch splines.
