Good question, maybe I was too liberal in the "05+ Frontier" fitment. I purchased these for a Nismo (ie M226), based on the fitment guide of Rockauto's website.Do you know if these are for the m226 or the c200k rear axle. Is there a difference between the ebrake. Someone should snatch these up with all the leaking rear axles. The e-brakes get coated with oil and stop stopping.
