This is a complete plated ZF limited slip diff which is a 3.9.2 ratio and ready to bolt straight in your car. Collection ideally from Nr Stansted Airport. It's still in my car if you want to come and hear it to verify it doesn't wine. Removing from the car this week - or if you want to give me a hand we can do it while you're here... lol Picture for illustration only, but that's what you're getting. I can post at cost, but would prefer collection. £900
