Fooey, the rear cylinders are junk too. The one that the bleeder screw came out of trouble free was packed with the same grease or dirt/sand that the front two were packed with and are beyond repair, and the one left(rear right cylinder) has the bleeder screw frozen into it. So, about the only thing I am going to be saving from them is maybe a bleeder screw and the metal push rod ends, from the pictures they don't come with the cylinder.
