I just acquired a 1977 810 Wagon. Its is killer shape with 102k original miles on it and i actually have the service books and everything! This is my first Datsun project as my previous are a 72 Celica, 68 Mini cooper and a 71 ford courier. I know there are not many of these left and have many questions about parts compatibility, interchangeability and where to find them. Any input is welcome. I will be scouring the forums but links are always much appreciated.

Welcome aboard! Super-cool - that's the predecessor to Nissan's Maxima, and they were way ahead of their time.

Most drivetrain components are likely shared with the Z of the same era (77-78). RockAuto, Amazon and car-part.com are great sources for late-70's Datsun bits.
