Well I did not have the correct one. The one needed is for snowflakes. Maybe someone has one. All I saw on treats were cev ones. You could adapt one of those to work and replace your vdo speedometer with a cev one. That would be the most direct way to use new parts that are immediately available from Treatland.tv there are many other parts websites to look around thru tho. Put up a WTB in the buy/sell forum. Be sure to specify snowflake speedo hub.
