My girlfriend has a 1988 e30 325e. She needs a new master cylinder, and on BavAuto there are 2 different ones: one from production 6/1988, and one for 325e thru 1988 production, but I do not know which one to get. Her vin number is WBAAE5401J8813862. Any help on how to figure out which master cylinder to get would be much appreciated. Thanks.
