Hi Joseph
You'll find it quite hard to get certain parts in the UK. The best way is to start with a part number - I can send you a parts book pdf if you pm me your email.
The numbers on the plates under the bonnet and on the engine are critical too when it comes to sourcing parts. Is yours an 845cc or 1108cc? If you're not careful, it's all too easy to end up with the wrong parts!
