help me fig out what rear end this is

[baginwagon]

not sure if u read the titel on here its a 4 SPEED so 200r4 350 turbo all that stuff dont apply to me sense i can just leave at what ever rpm works best lol
its is pretty dame quick out of the gate so i dont think its a 308
and its funny as hell that i can bang second gear and get rubber

and do the bags and maybe cam intake new carb pipes for sure
and my wheel and tire combo

3.08 is good compared to the other possibilities...like a 2.21:1 or 2.41:1 axle. Also, the 3.08 has a 3 series carrier so you can use normal gears with it and don't need a ring gear spacer or thick gear to work.
