Poundz9oh9 Posted August 9, 2003 Share Posted August 9, 2003 How can I tell if my 71 has an updated (ie..ZX) master cylinder? I've looked for pics, but can't seem to find any that would help me determine if the master cylinder has been upgraded. TIA Quote Link to comment Share on other sites More sharing options...
auxilary Posted August 9, 2003 Share Posted August 9, 2003 a ZX MC will be stamped with 15/16 on the side. The stock 240z one is stamped with 7/8 Quote Link to comment Share on other sites More sharing options...
evildky Posted August 10, 2003 Share Posted August 10, 2003 if it's an early 71 with verticle lines on the rear window, the front output of the master cylinder will have a "F" stamped on the side of it and the rear will have an "R" you'll have to lift the inspection lid and look real hard to see them, this is how the early 70-71 original masters are, makes them different from all the rest Quote Link to comment Share on other sites More sharing options...
