i know that this has been answered but i cant find it. if i am looking at a tag on a rear end.. what will the tag say if i am looking for a trak lock.. posi.. or whatever you want to call it.. someone said that there is a letter on the tag that specifies if its a trak lock rear end.. obviously i can spin the wheels and both spin the same direction.. but if the car is on the ground, this doesnt work too well.. thanks
