There is really no such thing as a type 1 flywheel, but there are both 6V (180mm) and 12V (200mm) flywheels, both of which were used in both types of cars. There is also a crossover flywheel, which has the 6V ring gear and takes the 200mm clutch. Whichever flywheel you use, you really should use it with the correct crank. There is one way that you can "mix and match" but I don't recommend it. If you already have one of the crossover flywheels, then you can just continue to use it and your 6V starter on 12V. Just don't go cranking it too long at a time. If your notch has the 6V/180mm flywheel, then you really should change to the later 12V/200mm flywheel and the late matching crank. There are lots of reasons why this is preferred. The crossover flywheels are quite hard to find. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
