the conversion armatures are only for the SWF brand wiper motors single speed up to 1966 won't work with 1967-1969 bug 1974-1974 thing 2 speed wiper motors or Bosch or Avogg wiper motors.
They make them for the Bosch motors as well. www2.cip1.com/ProductDetails.asp?ProductCode=VWC%2D113%2D955%2D811%2DC As for the 67+ models here in the USA to they were already 12v so no need to convert them.
I really mean that you don't show the armature working once installed in the car itself. It's very important to see if the wipers stops just at the right side or not and seeing the speed as well.-
They returned to the parking position as they should. The armature has no control over that, it is in the wiring of the wiper and switch that controls that.
it will run very fast cause the wiper arms to slip out of position on the wiper shafts as well the motor will coast past park and the wipers won't stop it won't burn out but run too fast on 12 volts
it will work on 12 v but will coast out of park, and can knock the wiper arms out of position on the wiper shafts. you can use this armature or get a 1967-1969 12v 2 speed SWF wiper motor
Black Phantom I showed it operating at the 6:00 mark. As for removal of the unit from the car, it is only held in with one bolt and the two nuts on the wiper shafts. If you are having trouble removing the unit, I suggest you find a mechanic to do this conversion.
