Drive coupling became frozen and brittle, broke off.

I entered the model number of my blender and was given a list of potential matches to my NLA appliance, all of those still available listing the same part number for the coupling. Diagram also matched. Clicked on repair video which showed just how to remove the old and replace with the new. Ordered online and hubby muscled it off per video instructions and I screwed on the new one per very clear written instructions that came with the part, which came within a week or so of the order. Back in business!
