91 z28 rear end
 

how do i find out what diff an gears are in my stock camaro cause im thinking about upgrading to like 3.73 gears or somin a lil better an i need to know

jack it up and spin the wheel (both off the ground trans in neutral) count the number of turns the drive shaft makes compared to the wheel. See if there is a number on the axle tube, or look for your rpo code on the sticker in the console

ight so is it in the console like do i ahve to take it apart an its near the shifter or something?

open the lid look at the black and white sticker (I think it was in the console seems like mine was on the lid)
