I would recommend replacing the bearing just to be safe. It does not have the spider gears or I think they are also called the pinion differential gears as the shaft broke and damaged the pinion. The ring gear is intact without a scratch. Came out of 1966 f250. email please with phone number for quickest response thanks
From all the info that I can gather these are 30 spline. You get both left and right shafts, 2 shims and 2 gears that go on the ends of the axels all for 100. They measure 33.5 inches from the inside of the flange to the end of the spline email please with phone number for quickest response thanks
