So, the rear in my car is done for (car is still moving but don't know for how much longer). My uncle refuses to spend the 8+hours he says it will take to rebuild it, so to replace it would be the best bet. Does anybody know of a way to figure out the rear size without having to open the casing and draining everything? All the info I have found (with the help of Mustang Boy) has said that its either a 2.73 or 3.08 - keep in mind I will be replacing the entire thing, so everything has to just bolt up and go. Thanks!
