VW Type 3 (Squareback, Fastback, Notchback)
Always buy parts based on VIN numbers, do NOT trust the year written on your cars title. e.g. A Squareback made in Germany in June of 1966 might have sat on a US dealership lot till the following year. When sold, the vehicles title would state the car is a 1967. Parts purchased for '67 may not fit a 66.
Not sure what your car is? Check the VIN number is located under rear seat on center tunnel Chassis ID Plate. Depending on year may also be either behind the spare tire (pre-69)or in the door jamb and on the dash (post 69-).
