Well kinda... A ring gear presses on your flywheel, a crownwheel bolts on your differential. What do you call a crownwheel and pinion over there? The 202 box has improved syncros and obviously newer than anything else. You will have to swap the speedo drive and your gearbox mounts over plus the starter needs changing and I'm not sure if your current ring gear (ie flywheel) will line up with the new starter. I'm curious about your noise, you say it's only on deceleration? There's no hassle changing gears etc, is it a high whining sound or a low rumble? What is FIPG? - Silicone or gasket sealer The vibration - Is it constant or only when moving in gear? Does it go away when you press the clutch in?
