Does anyone have any experience with what the "O" ring dimensions should be for the shaft that the yoke needs to seal? I don't know what kind of deal they used to stop the oil from leaking out of the rear. I am really not certain that they used a conventional "O" ring or something else in the "groove"?? We could sure use some words of wisdom from someone who has worked with this.
