Its a 1953 3600, but you are right - the 235 engine was updated with a later year 235 - casting indicates from 1958 to 1962.... but my problem is that the throttle rod is attached to a barrel sort of connector, and from what I can tell there is NO cotter pin to connect the cable to... look at this picture below. Unless the hole is being hidden under the part where the linkage attaches to the carb?
