I am uneducated when it comes to Mazda Protege DIY repairs and enlisted the help of a friend of mine to change out the spark plugs/wires. However, when he was changing them out, he inadvertently broke a part. I need to replace it but I am not certain what it is called to order it. I am new to this forum but would really appreciate any assistance that anyone could provide me with to identify the part name/number. The part that I need identified is circled in red. Thank you so much. Derek
