We're having problems getting her tuned, but that's not my question

That is my coil coil bracket. It snapped in half within 100 miles of the kit installation. Also, I was 5 miles from home and had to push her all the way. When we went to the shop to order the part, they couldn't find the part number because they had never heard of one breaking before. Finally got the part ordered and installed. (Takes all of 5 minutes to do.
a week later, same part snapped in the same place. This time, i was only 2 miles from the scooter shop. Pushed her there. My favorite club mechanic had made on of these brackets himself, when we had difficulty ordering the first replacement. I called him and he brought it over.
This one was made of steel. We were sure it would be okay. Wrong! The second time I rode, I pushed Stella home. Fortunately, I was one a mile from my house.
Anyone heard of this happening. All 3 piece fractured at the same place.
