I'm aware that the 91 troopers came with either 4.56 or 4.77 but how do you tell what you've got? Big tire package came with 4.77 but how do you know if you got the big tire package? I've only owned it for 2 years so who knows what tires have been put on it since it rolled of the factory floor, I've got 35's on it now.

One more thing, did all the LS models come with limited slip diffs? Cause I've got the LS and can't tell if it's limited slip or not, just want to put a locker in it.

Thanks
