These are the EARLY 1963 - 1965 syncrho assemblies that use the straight, non shouldered brass. These are new and in very short supply, if you wish to keep your early Muncie completely original with genuine assemblies, these are it. When these are gone they will be gone, (as in not any more being available), because most rebuilders use the late style in their reman jobs.  FOR THIS ORIGINAL "EARLY" ASSEMBLY, CALL FOR AVAILABILITY.
