It must have been Jeff. I had gotten some other M5 parts from you a while back, front grille I know, parts worked well. Is this the part you are referring to Brian? This is from an M5 parts book, part number 10A12171 tachometer drive diesel. As Shaun said they were used on the 5 Stars as well (same number in parts book). I think they must have used these on the gas 5 Stars as well as I have one on mine.
