1. Safety Precautions:
* Disconnect the battery: This prevents accidental shorts while working near electrical components.
* Use jack stands: Never work under a car supported only by a jack.
* Wear safety glasses: Springs and other parts can fly unexpectedly.
* Work in a well-lit area: This helps you see all the adjustment points clearly.
2. Identifying the Problem:
* Misalignment: Is the hood uneven, sitting too high on one side, or off-center?
* Rubbing: Where is the hood rubbing? On the fenders, radiator support, or elsewhere? This will pinpoint the area needing adjustment.
* Latching Issues: Does the hood latch properly? Is the hood release cable working correctly?
3. Adjustment Points:
The hood's alignment is controlled by several points:
* Hood hinges: These are usually located at the front of the hood. These hinges often have adjustment slots or bolts allowing for vertical and horizontal adjustments. Loosen the hinge bolts to allow for adjustment.
* Latch mechanism: This is the mechanism that secures the hood to the body. Adjustments might be possible within the latch itself, or adjustments may be needed to the striker plate (the part the latch engages with on the body).
* Radiator support: The radiator support can sometimes be slightly bent or misaligned, affecting hood alignment. This would require more extensive bodywork.
4. Adjustment Process (General):
1. Locate the adjustment points: Carefully inspect the hinges and latch mechanism for adjustment slots or bolts.
2. Loosen the adjusting bolts or nuts: Use the appropriate wrench or socket.
3. Make small adjustments: Move the hood slightly to achieve the desired alignment. Make small adjustments at a time, checking for alignment after each adjustment.
4. Tighten the bolts or nuts: Once you have achieved the desired alignment, tighten the bolts or nuts securely.
5. Test the latch: Ensure the hood latches securely and closes properly.
6. Re-check alignment: Double-check the alignment to ensure it's correct.
5. Specific Issues and Solutions:
* Hood rubbing: Carefully inspect where it's rubbing. If the fenders are slightly bent, this is a more significant body repair issue. Minor rubbing might be solved by adjusting the hinges.
* One side higher than the other: Adjust the corresponding hinge on the higher side downwards.
* Hood not latching: Check the latch mechanism for proper function and adjust the striker plate if necessary. The release cable might need adjustment or replacement.
6. Resources:
* Factory service manual: A 1971 Plymouth Road Runner factory service manual will provide detailed diagrams and instructions. This is the best resource for accurate and precise adjustments.
* Online forums: Search online forums dedicated to Mopar muscle cars. Owners may have documented similar issues and solutions.
* Experienced mechanic: If you are uncomfortable working on your car, consult a qualified mechanic specializing in classic cars.
Remember, these are general guidelines. The specific adjustment method might vary slightly depending on your car's condition and any modifications made. Always prioritize safety and take your time to avoid damaging your vehicle. A factory service manual is your best friend for this task.
