Go Look at the production date in the drivers door & let me know.. HaHa!!
The 71 & 72 Super Beetle had a flat windshield = No Dash & smaller rear tail lights
IIRC those rear lights came into existence in 1973
In 1975 it would have only one tail pipe = Fuel injected
73 & 74 are hard to tell apart BUT??
I used to manage a Import Auto Parts Store Called WIP Imports
Everyone there had a VW Mine was a 1966 6 Volt European Type 1
That's been 35 years now but I am pretty sure about that..
I now have a 2003 Convert on it's way to the salvage yard SOON!!
