After I purchased this car I have found many parts that are not the same as the normal production 914-6.
Note the black hose connector cap on the washer bottle
This bracket is located under the dash, I am not sure what it was installed for.
The speaker grills are made of a thin plastic with hand cut slots.
The serial number on the engine is on the fan housing support (like the 911) not by the thermostat (like the 914-6).
The "engine type" sticker indicates 914 instead of 914-6.
The fresh air dash vents are made of balsa wood instead of plastic.
The center tray is much like the standard except it has no divider.
