Those are just casting numbers. There was a tag on the cover bolts that told you the ratio. All you can do now is pull the cover and count the teeth.
 
None are the gear ratio. (That might have been on a tag on the stock rear cover).
Now you'll have to pull the cover and count teeth.
Pnora tree'd my by a minute. I type slow, lol.
Edit:well there are other ways, without pulling the cover. Check out some you tube video's.
 
Well, you could spin and count turns too.
