Option Codes
 

I have a 1974 911 and the original window sticker that came with the car. It lists an "Option Group - K20 at $950 which was nearly 10% of the list price. I have not been able to find any information as to what that included. The car has 911S/Carrera instruments which was optional and must have been part of this K20.

Does anyone have material that even list "Option Group - K20"?

K20 Wimbledon green carpet?

From several similar threads the single alpha prefix with 2 numeric characters seem to relate to the interior configuration.

Partial, full leather, color coordination of the cig lighter with the gas tank sort of thing. There is little to no info available.

If you can find a factory stripped to the nub car without "deletes" you can begin compiling the list of stuff on yours that is different.

Tough task.

number manufactured
 

Along these same lines, Is there any information out there to determine how may car of a particular color/interior combination were made. In my case I have a GP White with White leather 79' SC. I have been trying to locate the number of 911 SC made in this color combo.
