I would say it depends on the goal you have for the car. Besides just being NOS, parts need to have the correct date of manufacture to be 100% correct. For example, parts made in later 62 or early 63 for you 1963 car depending on where it fell in the year's production. Not every car show will hold a car to these standards either. Mainly, it is how much you want to spend and how much you personally desire the car to be exactly like it left the factory. I don't really believe there is a wrong answer as long as the Imperial lives.

This list is an incredible resource for me since I am completely new to all of this. Question #1: I purchased a the car from my uncle a few months ago. He said that he bought it 6 years ago from the original owner and that it has been garaged and everthing is original. How do I determine if it is original or has had items replaced such as upholstery? Question #2: I have had a local mechanic replace the water pump, fuel pump and plug wires. After all of that, John sent me an excellent description of NOS which I posted earlier on the list. Now I am wondering if I have made a mistake by replacing these items without searching for NOS parts. If I were to enter the car in a show as an original that is driven often, will this hurt me in the judging? I now need a compressor for the A/C but am waiting to determine if that needs to be NOS as well. Hal Coble 1963 Crown Imperial Southampton Georgia
