If your going to show the car then you should also consider that your looking for examples built at the same plant and production period as your car. Plenty of differences between plants that year.
Also consider that if you only find one example and you copy it exactly you will be copying their mistakes along with the correct details. Few if any cars are restored perfectly correct in any area of the car.
Might consider looking for unrestored original cars from same plant and time as they are valuable resources and are not someones interpretation .
Also consider cars with other engines since the non-engine related details will be shared with your car if its same plant and time. Finishes, hardware, direction of hardware installation and so on types of details for example
Just thought I should mention those points
