I'm not much of a 'Original Guy' but for fun here are the things I picked out that are not correct,
-Overspray, wrong fuel pump, top throttle bell crank should be straight, brake master cyl caps, speakers in doors, wrong radio, missing bumperettes, headlights, P/S mirror(shouldn't be there), wrong D/S mirror, wrong antenna, wrong wheels, some kind of lock just to the left of P/S brake light, front marker lamps upside down, wrong wiper blades, shifter boot colour might be wrong, rear deck carpet from a later year.
What did I miss? The only clue that there might have been a colour change is that little splash of Datsun orange paint just to the left of the P/S shock tower data plate.
Looks like a solid $14,000 car in need of complete restoration to me.
