914’s have always had a 12v starter and entire electrical system is 12v (IMG:style_emoticons/default/shades.gif)

You mentioned a bushing, 914s starters don't use the shaft end bushing. Are you working with a VW/bus/Vanagon trans? Need a lot more information here. |

If you’re asking about a VW beetle, the 6 volt versus the 12 volt starters had a different number of teeth on the gears. They also had different flywheels with different teeth patterns.
But, yes IIRC there is a conversion bushing you will need, in addition to a different starter, battery, flywheel, alternator/generator, wiper motors, etc. |
