Ok so I took my 76 pbass into a local luthier for a neck issue. He did a nice job but informed me that my body was a '72 and the neck is a '76. I always thought it was an original '76. Now I know Fender kept some stock and matched pieces when needed of different years. BUT, do I have an original '76 or do I have a bass replaced with different components over time? Does the age difference sound possible that it is still original?? Im a little bummed right now..
