right,removed a c16xe from a p.a.s gsi,and putting it into a non p.a.s corsa, the problem im having is the gearbox mounting onto the gsi body is different to the one on the corsa its going into. the gsi one sits lower and further back,so when i place the mounting up against the gearbox,it lines up with the holes on the box,but is too long,so goes underneath the mounting on the body,the only thing i can see is the rear gearbox mounting rubber is facing the wrong way(arrow facing towards the back of the car),but surely this wouldnt cause the gearbox mounting problem,would it?

any help would be greatly appreciated guys
