Gearbox mount problems. Glanza

[Luke91]

Ok guys started removing my box to say ready for clutch tomorrow. And I can't get the bolt to budge on the rear gear box mount at all l ( I'm on axel stands so leverage is abit of a issue). Now I was looking at the mount and it appears to be attached to the car with 4 big bolts would I be able to remove them plus exhaust and that anti roll bar thing?? Would that work or anyone done that before? Many thanks.
