I have some left over "mistakes":
1. a new steel pulley OEM 11-51-1-271.423 w factory sticker, this fits the "spin on" type water pump, the bolt pattern is a rectangle, this is a $300 plus part from BMW $175 plus ship.
2. a new "Uroparts" aluminum pulley for a serpentine ribbed belt, 11-51-1-436-590 - PRM square bolt pattern fits later BMW 3 and 5 series not the E9 $30 plus ship.
hope someone can use them.
