Adjusting the mirrors on a 1970 Dodge Challenger R/T is essential for ensuring you have good visibility and can drive safely. Given the vehicle's age and the manual mechanism of its mirrors, this task may seem a bit tricky if you're accustomed to modern vehicles with electronic adjustments. The mirrors may be found off-angle, causing limited or incorrect views, thus affecting your driving safety. Here's how to solve this issue and ensure your mirrors are accurately adjusted.

Step 1: Locate the Side Mirrors

The 1970 Dodge Challenger R/T has manual side mirrors. There is one on the driver’s side and, depending on the specific model and customization, possibly one on the passenger’s side. The mirrors are mounted on the doors, close to the front windows. They are encased in chrome or body-colored housing, typical of the 1970s design.

Step 2: Fine-Tune the Driver's Side Mirror

1. Approach the Driver's Side Door: Stand beside the driver's side door. Ensure the door is closed so you can adjust the mirror while sitting in the driving position.
2. Adjust the Mirror Housing: The mirror housing itself can be tilted manually. Gently move it up, down, left, or right to start the rough adjustment.
3. Sit in the Driver's Seat: Once the rough adjustment is made, sit in the driver's seat and close the door.
4. Fine Adjustment: Reach out through the open window to make fine adjustments. Aim to position the mirror so you can see the edge of your car in the inner part of the mirror and the traffic lane beside you in the outer part.

Step 3: Adjust the Passenger's Side Mirror

1. Approach the Passenger Side Door: If your Challenger R/T has a passenger's side mirror, follow these steps.
2. Manual Adjustment: Since the adjustment lever is not available on this model, you'll have to manually tilt the housing gently.
3. Sit in the Driver's Seat Again: For fine adjustments, sit back in the driver's seat.
4. Ask for Assistance: Due to the awkward angle, it might help to have someone assist you in adjusting the mirror while you sit and guide them.
5. Fine-Tune: Adjust it to maximize your view of the traffic lane to the right without significant blind spots.

Step 4: Evaluate and Fine-Tune

1. Check Visibility: Once both mirrors are adjusted, take a short drive or practice parking in a safe area to test the adjustments.
2. Readjust if Necessary: If the mirrors don't give you an optimal view, readjust them as needed following the steps above.

By following these steps, you can ensure your 1970 Dodge Challenger R/T's mirrors are correctly adjusted, enhancing your driving safety. Adjustments may need to be revisited periodically due to vibrations and general use.
