A833 43 tooth speedo gear.

You must be running a small tire in the rear, generally with standard tires (around 27" dia.) the speedometer gear will run about 10 times the rear end gear. For example a
3.23 gear= 32 tooth speedometer gear
3.55 gear= 35
3.91 gear= 39

You might want to check that gear before you buy one. There`s a formula for getting the correct speedometer gear and you should be able to find it in the tech section here.
