rear gears
 

th ese are the numbers off ring gear how do i "read" them or what ratio do i have E47W AA-11 41 7Kd & a small triangle at the end

You count the teeth on the ring gear, and divide by the number of teeth on the pinion gear. The result is your gear ratio. keep in mind, that the gears are a matched set. You can't just change the ring gear, you have to change both the ring and pinion gears.

Take care,
