As a now former 510 wagon owner I see all kinds of issues with this one.

A few years back I had a rolling project car, 1971 Datsun 510 wagon. I told my (ex)wife I bought it to supplement my Datsun 280z daily driver since I needed something to haul kids in. I spent a lot of time and money modifying the 510 and at the time had just put on dual side draft SU carbs with a custom 2" exhaust.
