Yes, on the original unrestored, the edges are perfect. They measured exactly 15/16" all the way around the driveshaft. That is first photo in this thread. Up close, they look mechanically applied, or someone with a very steady hand. That driveshaft has not been out of the car, the U-joints are original, as are the differential, trans, and engine. 25,000 miles. (The diff is making noise but I don't want to disturb anything especially given the amount of miles that I drive a year.)
