My 73 Z is my second one, I had another 73 back in 1980 and sold it in 1985 which was a mistake. I converted both to round top carbs my first on I bought from Datsun the second set came from Ztherepy.
I bought part cars for certain parts, a non running 71 that was a rust bucket for a set of American Racing libre mags that were mint. A running 72 for the 4 speed and clutch pedal assembly and a bunch of spare parts. Finally a totaled 280Z for the running engine and the 5 speed.
