Just finished reading all of the information concerning this topic so here goes the questions. 1. Install both of the rubber ( rags) ? I agree that it should be that way but my instructions say with a coaster brake, just put the inside one on. 2. They sent self locking nuts but do most of ya put both on the nuts, lock washers and lock nuts? This has turned into a challenge and I am gonna win. Really leaning to a hub adapter and sprocket. Better I know. Those coasters are ****. I sure know them in and out now. Just got to get some cone wrenches so I can get the wheel like it should be. What a @#@%$#%#$. No problem when I was a kid. lol thanks and will be watching.
