We really need to know what ratio is fitted at the moment,so that an alternate can be suggested.
Your car could have either a 4:1 or a 4:27.....slide underneath the back of the car and have a butchers,take a wire brush or a bit of abraisive paper with you along with a torch.You are looking for a tag held on to the back of the diff,this will give the ratio,but the tag will be rusty!
