I have to agree with Rubi4MyMrs about the whole distributor/gear replacement thing - As someone who is old enough to have worked on a lot of carbureted vehicles with conventional distributors, distributor replacement was a fairly normal thing, and no thought was ever given to needing to reuse the original gear. You simply got a distributor from a parts store or a junkyard and plopped it in. Fire and brimstone did not fall from the sky, and everything was fine. A properly hardened surface with no unusual wear should be able to handle this.
