how can i find the gear ratio for my 95 legacy awd 5speed i look at the rear diff and the is just a couple number stamped on the very bottom first it says 314 then a bigger stamped number 51 below then it says KN41

now that i think about it, sometimes i think the diff number could be "up higher" on the rear foil stamp and covered by the bar that the diff hangs from.

 

you can turn the driveshaft and count how many times the wheel turns. or turn the wheel and count how many times the driveshaft turns...you get the point.

 

39 for every 10 would be a 3.9 ratio

41 for every 10 would be a 4.11 ratio

etc....

 

from what i'm seeing on that chart, the impreza in the yard should match up to your 95 legacy, but you are wise to double check!
