I've just received my Conways clutch for my Comet - looks a very nice piece of kit. I am planning on fitting it in a couple of weeks. With regard to the filing of the splines to fit, can anyone tell me (in their case) how much filing was necessary, and if it was the top and side of the splines on the clutch or also the bottom parts that forms the circumference that the splines stick out of from? How tight was the eventual fit - I don't fancy having to tap it on with a mallet (as it says in the instructions) if possible. Any other experiences or advice on fitting would also be appreciated. Thanks.
