Differential and gears

I'm having difficulty finding out for sure if I have an AMC20 or a dana. I own an 82 CJ7 . I am also having difficulty finding out if it's a wide track or narrow track. I've read that 76-81 are narrow, but I want to find out how to make sure. And I'm also wondering how to figure out the gear ratio without tearing the rear apart. The kid I bought it from wasn't 100% sure but thought it was 3:31.
