Here I've found several very useful sites you can use to find parts, cross reference part numbers and dimensions as well as check chassis options via VIN.   http://www.oemepc.com   http://www.vehiclepartsdatabase.com   http://optikoop.com.mk/autoparts/   http://carinfo.kiev.ua/cars/vin/skoda   * ECP Buying tip, I've found their ads on eBay are cheaper than in store/online even with discount codes.  Also look out for package deals e.g. 4 discs+pad
