Official GMM hand model
I found this on ebay and know for a fact these gear vendors will not work in reverse gear. The asking price seems really fair but please ask the seller more questions why this is not a working part. Also call the factory and ask them what this unit is by telling them the serial numbers. They can tell you what year it was purchased and what model it is. They made a "J" &"P" model. The P model is the newer model most have or want. Look at the speedo drive housing size. The larger one thats about 2 inches diameter is the P models.
