Bought a Volvo 245 -82 12V rear wipermotor. The wipermotor is found in Volvo 145 and 245 years 69-83. Marked SWF.
Here the Volvo's wipermotor vs. -66 beetle 6V wipermotor.
Opened the two motors and changed the magneto and rotor from the Volvo motor into the -66 motor.
Goes right in without any modifications.
Here is the finished products:
One 12V wipermotor for Beetle -66 and one 6V wipermotor for Volvo.... :D
