I ordered two of these blanks a few days before I went on a business trip back in September. The package shows up while I'm still on my trip. My wife accepts the package and it sits in the house. Fast forward it a few months later. I open the box and put the blanks in my tool cart. Last night, I put one of the blanks into my lathe and begin turning and realize the blanks GM sent weren't stainless steel but SKU #762BLANK-17.
