Just had a problem yesturday after a great day at winton historics, neighbour had his v8 manual torana sitting on his driveway, roughly same angle as ours with the handbrake on, he thought it was in neutral and let the clutch out.
BANG! one of the loudest mechanical noises i have heard in a while.
I thought he has blown the clutch or first gear, but on inspection it has snapped an axle, bloody banjo diffs and steep drive ways dont mix!
