Genuine Harley
Rear Brake Master Cylinder for Dyna models
Should be direct fitment for 91-05 Dynas to the best of my knowledge
Pulled from a good running 2001 bike
Fitment is completely up to you
Harley Part number is 42474-90C
Used. Works as it should but it is not new and you should examine photos carefully and expect normal wear and cosmetic imperfections
