I ordered the PST polygraphite rebuild kit last year. After reading a number of posts recently, I decided to order the greaseable pivot shaft kit. I just received it, and I am very impressed with the quality. The pins actually have Proforged stamped on them. The bushings are a light press fit onto the pins. I tried to press the bushings in the new shells, and I could only get them started with hand pressure. The pins are not stepped down, so no inner sleeve is necessary.
