What do you need to know?

See, I am considering upgrading my rear gear and would like to get power to both wheels. But I would like to know what I have now so I can get a starting point. Is there a way to figure out what rear gear I have?

What gears were available in '73, stock?

See VIN info here at Classicponycars.com

To help identify which rear you actually have, see Rear end info here at Kevinstang.com (8" info at end of page).

I got it! I had a 6 on the Data code plate so that means I have a 3.00 standard gear.
What kind of difference would I feel if i installed a 3.50 locking differential?
How much impact would there be in my MPG? I do alot of highway driving.
