Hello all, I just wanted to get a sanity check on what I'm seeing. On the rear output shaft, the rear end where the needle bearings get installed, in I'm seeing vertical stripes. I don't know if this is wear or if they were machined in and are supposed to be there. They look really clean and almost intentional. Also, what helps to complicate things is that I apparently have a weirdo metal drive speedo unit. I removed the snap ring and washer for clarity. I can't find any clear pictures on the internet of what it's supposed to look like. Thanks for your help!
