Really I thought the axles used with the lsd has one side longer then the other one and I thought Ive seen a picture where even the stubs were different. If this isn't the case it should make things alot easier. Didn't they switch the tone ring from the hub to the axle on some of imprezas? Sorry if my info is wrong, just want to make sure I buy parts only once. I don't know if it makes a difference but I'm talking about usdm imprezas
