Snow Joe Replacement 2 Auger Blades

I purchased this Auger (2 in poly bag) about 2 years ago for my Snow Joe. I have an older model and did not know that they had changed the auger blades on later models. Anyway these are new in bag and I do not need them as they will not fit the older models with 4 blades. Hope you can use these. Check your model to assure you have the 2 large auger blades. These are the newer ones.
