Does anyone know there appears to be 2 factory p/ns- but in the aftermarket they appear to only make one part.

The factory calls out a 104 part for the magnet on a M119 engine where and the 120 engine takes the 119 part??

Aftermarket suppliers are listing only one part... and the 119 050 10 77 less than half the price of the 104 part.

They're slightly different shapes - this explains it.

very helpful Justin,

Noting at the bottom of the second page- for service only use the second design. Looks like with the updated magnet, you'd want to replace the armature also as it goes from 21 to23 mm in diameter.

Correction- longer not diameter... Sweet, they might drop in.
