Trying to use the wrong springs could lead to:
* Poor handling: The car might handle poorly, feel unsafe, and be prone to accidents.
* Ride height issues: The car's ride height might be incorrect, leading to rubbing and other problems.
* Premature wear: The springs and other suspension components could wear out prematurely.
To be absolutely certain, you should compare the part numbers of the springs from both vehicles. A parts store or online auto parts catalog can provide this information. Even if the part numbers are similar, there's still a chance of incompatibility. It's best to get springs specifically designed for the Lincoln Town Car.
