RE: Anyone have parts for a old g38??
I believe you can use the newer style flywheel from Horizon with the older hub if needed. The older hub is just the nut that holds the flywheel. The newer flywheel is trued and tapped for the newer style hub to bolt on. It is held on with a nut and washer that is covered by the newer style hub. So, the older style hub should work just fine with the newer style flywheel.
