1975 Kolchak CHOPPER

In 1974, I was 10 years old and one of my favorite TV shows was Kolchak, the Night Stalker starring Darrn McGavin as Carl Kolchak.
This episode aired January 31, 1975. Episode 15: CHOPPER.
Kolchak narrowly escapes death when a motorcycle driven by a headless rider attempts to run him down on the streets of Chicago.
Land development disturbs the final resting place of a headless, sword-wielding cyclist who hunts down and beheads the rival gang bikers who killed him.
