How to remove and replace the ignition switch cylinder in a 1976 chevy cheyenne 1/2 ton pickup?

It would be the pickup in the bottom of the distributor.

No power where ? What happen's when you turn the key to the start position ? Does the starter engage an spin the engine ? Need to give better info.

RPO Z77 was the 1980 Chevy Sport/GMC Street Coupe exterior graphics packages that exclusively used the cloth seat with the addition of the floor carpeting, deluxe front grille, and deluxe instrument cluster. The option also included Rally wheels as standard, was available only on the 1976 to 1981 Chevy/GMC short bed 1/2 ton pickups.

Does the pedal go to the floor?? If so it is the master and the slave, they are replace as one unit of repair. If the pedal is very stiff but doesn't go to the floor you have a failed clutch.

This plate is the steering lock plate.It has a lock ring on the shaft but is under very heavy spring pressure which must be compressed in order to remove and re-install. There is a special tool that compresses this spring.It mounts on the steering shaft threads and pushes on the plate.It is quite difficult without but can be done with two persons as one presses and the other removes the lock ring...good luck
