Hi I have a ZX 1.4i Dec 1997 model 92,000 miles. I am trying to replace the clutch. I am having trouble removing the gearbox. There appears to be 4 bolts holding the gearbox housing to the engine but having removed the bolts the gearbox will only shift apart a few cms at the top. Gentle levering has not helped. Does anyone know if there are hidden bolts? Or is it likely that I need more forcefull levering? Many thanks.
