General question about parts...

Hi, I have recently come across an original owner 1965 Barracuda that has been sitting in a garage for at least the last ten years but most probably longer. I don't know the current condition of the car, whether or not it ran when parked, engine, options, whatever. In fact, I have never even seen it. I know the owner and he has recently started dropping hints about getting rid of the car. My question is this: How easy or difficult is it to locate parts for these cars? I noticed that Year One starts their Chrysler catalog at 1966. If anybody could provide me with some information so I can make an informed decision on whether to go after this car I would appreciate it. Thanks in advance.
