Got everything undone ok at hub end and just need to get driveshaft out of gearbox. Haynes book says use prybar against gearbox keeping inner cv joint level so as not to damage oilseal. Used prybar, or large flat screwdriver in my case but no sign of driveshaft coming out at all. Not sure how much force I should be using without risking breaking anything. Got new circlips ordered just incase.
