Need rear Master cylinder 83 GL1100

[IVGOT2WINGS]

Need a replacement rear Master cylinder for my 83 Wing rebuilt mine but fluid still leaks from stem! I either screwed the pooch or it's dogged tired either way I'm riding with no bake brakes!! If anybody has one please shoot me an email @IVGOTWHATITAKESAOL.COM Or if anybody might know why or how I screwed this up PLEASE advise as you're more wise!! Ride SAFE people in other words have rear brakes!! THANKS...... Tony
