NOS means New Old Stock - and is used to designate an item that was made when the cars were new, by the original factory, and stored for all the years since. NOS parts are sought out because they are sure to be authentic in all respects. However, one does have to be careful about shelf wear and deterioration from age. For instance, an NOS tire would be useless, as would most other rubber parts, unless they were stored in a hermetically sealed package. NOS fuel pumps, for instance, will fail in a few miles, because the rubber diaphragm is old and brittle (and also because the old fashioned rubber compounds can't stand the new oxygenated fuels).

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.
