Disconnect the negative terminal from the battery to isolate the electrical system. This will prevent electrical shock. The ignition switch is inside the steering column. Remove the steering shroud to access the ignition switch. You will need a Phillips-head screwdriver to separate the shroud and expose the column. Unscrew the screws holding the shroud together and pull them out. Lift up on the top half of the shroud and separate it from the column. Then pull down on the bottom portion and work it loose from the column.
Removing
Locate the ignition switch settled along the steering column, and unscrew the small screws that are holding it to the column. Pull the wiring harness out of the back of the ignition. The harness will have a tab that you separate from the sides to pull away evenly from the switch.
Installation
Place the new switch where the old switch was positioned. Start the screws to ensure the switch is properly aligned. Tighten the screws with the Phillips-head screwdriver. Now attach the wiring harness to the new ignition switch. Push the harness into the receiving end of the switch until it clicks. Tighten the steering console shroud around the column. Reconnect the battery so you can start the Buick and ensure it cranks.
The ignition switch is wired incorrectly, is damaged,or a wire is damaged and contacting the starter relay circuit .

Pull the turn signal arm toward you.
There is a button on the back side of the switch that you push and hold while you pull the light knob out Forward. After this you can unscrew the hand nut either on the front or back of the switch that allows removal of the switch.
The core support is the (metal) framework that holds the radiator in place. This should be true on all vehicles that I know of.
They are structural, so, you have to cut them off, and weld the new ones on.
It looks like 68 mm
Some of the Beetles never came with a reverse light. My earlier '68 at least did not have one. The present '68 that I own has a reverse switch just above the gear box. Check for wiring or connection faults. If okay, your reverse switch is faulty. If you are having a Beetle that is. ---- Jas
