Parts Interchange List
Page Revised: 10 May 2019
TThere are quite a few interchanging parts between your Cougar and other Ford cars. When searching for any of these parts, we suggest finding a vehicle around the same model year as yours, and preferably a Cougar or Thunderbird, just to be safe.
NOTE: If a specific part for your car is not listed (ex: interior sail panel), that means the part is specific to your model only. If it is listed, it is done so for clarification purposes or known issues associated with an interchange attempt.
