I'm for leave it as is. N.O.S. I have bought many many N.O.S. body and trim parts when I did my 59 Plymouth. It is A standard term, and have got very good quality pieces,some still in factory wrap.As far as carb. parts, rubber, gaskets,etc. etc. etc. use your head!! Many parts I get CANNOT BE FOUND. And parts cars and junk yards good luck. Most are worse than what I have. I will always look for the N.O.S. term. And I don't need to hear "we're talking Buick not Mopars. It is the same across the board, I own both, when parts are scarce you get what you can. 99.9% of the time N.O.S. is better. alot of stuffs hide in the nooks, crannys. It was New, but Old Stocked never used is the way I see it. Just my thoughts. Mark
