I picked up a factory sealed 3.73 rear differential. They come fitted for the manual transmission. In order to convert for the automatic, you need to remove the pinion flange and install a new one. See Pinion Flange Kit part# M-4851-M8A. Has anyone here made this conversion? I am in the process and have some questions. I got the old flange pulled. Installed the new seals. Getting the new flange on the splined shaft – requires a special service tool – that I don’t have. Short of driving it on with a hammer, what are you folks doing to install?
