Hey Goose, I have a buddy that supplies correct date coded cores. He's not cheap but the parts you get will be clean, corrosion free and correct in all aspects. You will require a kit which he can also supply. He used to rebuild them but it wasn't worth it when he would get complaints and then find out that they haven't got a clue how to tune or install a filter etc.
e-mail me if you want to go that route.
