Pfft, thats not a heavy gearbox... My VR4's one was mucho mucho heavier-o!
Al - Your car for a while was making a hell of a crack when you took off, seemed kinda weird to me. Monster reckoned release bearing as well.
And even when they're "new" they can still stuff out. Ryan had one die after about 50km, just luck of the draw really I guess. Give me a yell if you want a hand with the box removal.
