* Different manufacturers: Buick and Chevrolet are separate brands with different designs and dimensions. Even within the same General Motors family, body styles and seat mounting points will vary.
* Year differences: While the 1960s were a time of relatively similar design, car bodies and seat frames evolved over the years.
* Power mechanisms: Even if you could physically fit the seats, the power mechanisms (motors, controls, etc.) might not be compatible with the Impala's wiring or electrical system.
Here's what you should consider instead:
* Finding Impala-specific seats: Look for power bucket seats designed for your specific Impala year and model. You might find used ones in good condition or look for aftermarket options.
* Adapting seats: With significant modification, you *might* be able to make the Riviera seats work. This would involve:
* Matching mounting points: Fabricating brackets or modifying existing ones to match the Impala's frame.
* Electrical work: Adapting the Riviera's power mechanisms to the Impala's wiring. This may be very complex and require specialized skills.
Important notes:
* Safety: Modifying seats can impact safety features and is not recommended unless you're an experienced mechanic and are willing to take responsibility for any risks involved.
* Cost: Consider the time, effort, and potential costs involved in adapting the seats. It might be more economical and practical to search for Impala-specific seats.
Before attempting any modifications, it's best to consult with an experienced automotive professional or do thorough research to understand the challenges and potential safety risks involved.
