What are they called again? The drive gear and what else?

The driven gear and drive gear.

lets say I have the 7 tooth and the other one is the stock for my 87(whatever that is). My speedo is off by about 30%. What would that make my rear end gear be?
Easiest way to check the rearend gear is to mark the drive shaft and mark the rear tire. Spin the tire 1 full rotation and then count how many times the drive shaft rotated? Then devide them and thats you gearing. peace1FatPony said:Math problem:
