The door jam sticker would have told you without a doubt. But doesn't 3000 RPM at 70 on 30" tires seem more like 4.56 gears? I had 4.10 gears on mine and I want to say on 30" tires my cruising RPMs were lower than that.

The search engine on this site is a very powerful tool. This question has been asked and answered here many times. I've answered it three or four times myself. Here's a link to a recent thread that's got lots of info on how to check your ratio. Happy reading.

you can use this site to help figure out which gears you have. couldnt 4.30s be a possibility too?

4.30 only came in automatics, so definetly not those.
I went to this site http://www.richmondgear.com/101032.html and typed in 70 mph/3000rpm/30"tire=3.83 gear ratio. No 3.83 ratio available. So, that don't jive.
Then I used the other one there, I put in 4.10/70mph/30"tire/.838 OD ratio= 2694rpm. So that don't jive either.
I put in 4.56, and it worked out to 2996rpm@70mph in OD(.838 ratio) with 30" tires.
So there you go. 4.56 That's how that works.
