Before you begin:
* Gather your tools: You'll need various tools including screwdrivers (Phillips and possibly flathead), pliers, possibly a socket set, wire connectors, and possibly a rivet gun or pop rivet replacements if your existing ones are damaged.
* Gather your parts: Ensure you have both headlight buckets, any necessary mounting hardware (screws, bolts, nuts, clips), and new bulbs if needed.
* Prepare the area: Work in a well-lit area with ample space. Disconnect the battery's negative terminal to prevent electrical shorts.
Installation Steps (General Outline):
1. Remove the old headlight buckets (if applicable): This usually involves removing the grille and accessing the headlight assembly from the front or the back of the headlight opening in the fender. This will involve removing screws, bolts, and possibly clips securing the old buckets in place. The specific fasteners and their locations will vary depending on the condition and any prior modifications to the car.
2. Inspect the new headlight buckets: Check for any damage or missing parts. Make sure they are in good condition before installation.
3. Align and secure the buckets: Carefully position the new headlight buckets in their respective openings. You'll likely need to align them with the mounting points on the car's body. Secure them using the appropriate screws, bolts, nuts, and clips. Make sure they are seated firmly and evenly.
4. Install the headlight assembly: This includes the headlight itself, along with any associated parts like the retaining rings or bezels. These are usually secured with screws. Ensure a proper and snug fit.
5. Reconnect wiring: Carefully connect the headlight wiring harness to the new buckets. Make sure the connections are secure and properly insulated to avoid shorts. A repair manual will show you the correct wiring configuration.
6. Reinstall the grille (if removed): Carefully put the grille back in place, securing it with the appropriate fasteners.
7. Test the headlights: Reconnect the battery and test the headlights to ensure they function correctly.
Important Considerations:
* Rust and corrosion: 1970 Challengers are old cars. Rust and corrosion can significantly complicate the process. You might need to clean or replace rusty or damaged mounting points. Penetrating oil can help loosen stuck fasteners.
* Body damage: If there's body damage around the headlight openings, you may need to repair that before installing the buckets.
* Wiring: The wiring can be brittle and break easily in older vehicles. Handle it carefully. If you have to replace any wiring, use appropriately rated automotive wire.
This is a general guide. The specifics will depend greatly on your car's condition and your access to a repair manual. Using a 1970 Dodge Challenger repair manual is absolutely crucial for a successful installation. It will provide detailed diagrams, torque specifications, and other vital information. Without it, you risk damaging your car.
