I was stuck needing blades for my SD and couldn't find the exact size. I bought some new blades that were close & can now change them at any old parts store. The 2 sides were different but that only means that a spare gets stored in the trunk when I buy a new set. (I'm cheap & buy the refills & not the blade.) I suggest measuring yours & match them up.
