Tach Drive Information
Tach Drive Information
I have a 66 2550 NC Monza. I have a tach drive that is missing the shaft and gear that goes into the head. Does anyone know how many teeth are on this gear. The output shaft has 12. I was told it was a 2:1 ratio but this does not seem to work with the drive as it would mean either a 6 or 24 tooth gear. 6 is too small and would not engage the output shaft gear. 24 teeth would make a large gear that would not fit in the drive. I hope someone can help me with this. I can get gears form the people who make right angle drives and I can make the shaft but I need to know what the gear ratio is for this drive.
