It has the correct steering wheel for '75. But the rev counter does not have the green band between 3 and 4 like the '74 cars I've seen. It should have a steering lock, the ignition switch should not be on the instrument panel. They had changed over to the lock on the steering column by 1972.
But it does appear to have the later 8 fuse unit and I think I can see the chassis number is stamped on the top of the right side suspension turret - that is correct for a 1975 car. Also the dip switch is column mounted, early cars have foot dips.
Looks like a 1975 car with the instrument panel from a much earlier car.
