914 anomilies, model year overlaps? Options

[1970 Neun vierzehn]

Well apparently (according to "World" information) some early '72/4s were delivered with non-inertia seatbelts, while later builds had the retractable belts.

'72/6s appear to have the ignition switch on the steering column, as do all model year /4s.

So I wonder, did the factory produce any 1972 model 914s with a fixed passenger seat, or conversely deliver any '71s' with an adjustable passenger seat?

Or, are there any 1971 914s that had fresh air vents on the outboard ends of the dash, or 1972 models that didn't have these vents?

My own '70/4 (build date 01/70; delivered 04/70) had the "appearance package" w/leather steering wheel, chrome bumpers, vinyl rollbar trim but did not have factory installed fog lights. The fog lights and their requisite grilles were installed at the dealer @ delivery. My car also was not equipped with the tethered "footrest" that the '70 and '71 models came with. My early car also did/does not have any headliner material on the f/g roof.

I was just wondering just what sort of other trim and equipment variations from spec have been noted.
