What frame do you have, and what's the paint condition? Are you repainting anyway? Are the lugs painted or chromed? Would a simple touch up of the rest of the paint suffice? Are you going for a wall-hanger or a rider? Are you trying to get it all original, or are you going to mix and match with modern parts? How steady are your hands? Have you done any filing before? Have I asked enough questions to drive you nuts yet? Should I ask more?
