Parts that are *likely* interchangeable:
* Many engine and drivetrain components: Unless there was a significant redesign (unlikely between consecutive years), engines, transmissions, and many related parts should be compatible.
* Interior parts (with caveats): Upholstery, some trim pieces, and certain electrical components might interchange, but be aware that minor variations in design could exist.
* Suspension and brake components: These are often similar between model years. However, always double-check part numbers to be certain.
* Body panels (less likely): While some might be very similar, slight changes in body styling could make some panels incompatible.
Parts that are *less likely* interchangeable:
* Electrical components: Wiring harnesses and some electrical parts can be different, even with seemingly minor changes to the car's features.
* Specific trim pieces: The bumpers, grilles, and other exterior trim can vary subtly between years.
* Instruments and gauges: While the basic functions might be the same, the specific designs could differ slightly.
Recommendation:
Before purchasing any part, always verify the part number with a reputable Cadillac parts supplier or a parts catalog specific to those years. Comparing part numbers is crucial to ensure compatibility. Simply relying on the year can lead to incorrect assumptions.
